There are many variations in the design of the screw type positive displacement, rotary pump. The primary differences consist of the number of intermeshing screws involved, the pitch of the screws, and the general direction of fluid flow. Two common designs are the two-screw, low-pitch, double-flow pump and the three-screw, high-pitch, double-flow pump.

The two-screw, low-pitch, screw pump consists of two screws that mesh with close clearances, mounted on two parallel shafts. One screw has a right-handed thread, and the other screw has a left-handed thread. One shaft is the driving shaft and drives the other shaft through a set of herringbone timing gears. The gears serve to maintain clearances between the screws as they turn and to promote quiet operation. The screws rotate in closely fitting duplex cylinders that have overlapping bores. All clearances are small, but there is no actual contact between the two screws or between the screws and the cylinder walls.

The complete assembly and the usual flow path are shown in Figure 17. Liquid is trapped at the outer end of each pair of screws. As the first space between the screw threads rotates away from the opposite screw, a one-turn, spiral-shaped quantity of liquid is enclosed when the end of the screw again meshes with the opposite screw. As the screw continues to rotate, the entrapped spiral turns of liquid slide along the cylinder toward the center discharge space while the next slug is being entrapped. Each screw functions similarly, and each pair of screws discharges an equal quantity of liquid in opposed streams toward the center, thus eliminating hydraulic thrust. The removal of liquid from the suction end by the screws produces a reduction in pressure, which draws liquid through the suction line.

The three-screw, high-pitch, screw pump, shown in Figure 18, has many of the same elements as the two-screw, low-pitch, screw pump, and their operations are similar. Three screws, oppositely threaded on each end, are employed. They rotate in a triple cylinder, the two outer bores of which overlap the center bore. The pitch of the screws is much higher than in the low pitch screw pump; therefore, the center screw, or power rotor, is used to drive the two outer idler rotors directly without external timing gears. Pedestal bearings at the base support the weight of the rotors and maintain their axial position. The liquid being pumped enters the suction opening, flows through passages around the rotor housing, and through the screws from each end, in opposed streams, toward the center discharge. This eliminates unbalanced hydraulic thrust. The screw pump is used for pumping viscous fluids, usually lubricating, hydraulic, or fuel oil.

Fluid enters the inlet before being transferred to the outlet via cavities between intermeshing screws. Due to the tight clearances slip is extremely limited, and mechanical action is highly efficient.

This is usually another name for a progressing cavity pump where a single screw rotated by a motor rotates within a stator. This is covered in our progressing cavity pump guide.

One screw is driven via the motor, with the other rotated by external timing gears at the opposite end of the unit. Screws can be mounted in pairs meaning up to 4 screws can be in one pump. All screws mesh together ensuring fluid travels along the screws from the inlet towards the outlet.

Triple Screw designs consist of a driving screw and two idler screws. The motor shaft rotates the driving screw which in turns rotates the intermeshing twin idler screws.

The lower the viscosity of fluids being pumped, the higher speeds at which components can be rotated at. Higher viscosity fluids such as Heavy Fuel Oil, molasses, bitumen or other slow flowing viscous liquids must be handled at reduced speeds to enable fluid sufficient time to enter the pumps inlet and ensuring cavitation does not occur. Lowering rotational speed also assists with the NPSH required by pumps.

Screw pumps are known to be efficient, due to clearances within the pump being fine. A gearbox is not always required, meaning mechanical efficiency is one of the highest when compared to other pumps such as gear or vane requiring such accessories.

Due to their design they are self-priming up to 7.5M. Providing screws are lubricated prior to startup, units can be ran dry for a limited amount of time.

Units are typically fitted complete with a relief valve protecting the pump from damage should outlet pipework become blocked, limiting the pumps ability to generate excessive pressure in such cases.

Providing screws are lubricated, units are capable of dry running making them suitable for tank stripping as they can also handle small amounts of entrained gas and air.

Screw pumps NPSH requirement can be as little as 1.5M with designs available for immersion in fluids where viscosity is high or NPSH available is low.

Due to the ability to alter pump speed through a gear box, pumps can handle a wide range of viscosities up to 35,000cst with changes in fluid viscosity usually having little effect on pumped flow rate.

Solid Handling – Models are not suitable for abrasive solid handling which can shorten screw life due to the tight clearances and abrasive affect. Coatings can be applied to reduce wear, but any hard solids >1mm can not be accommodated comfortably. Soft products such as polymerized rubber, mince, molasses, yogurt and Jams can be handled by such units without issue.

Part Replacement – Internal parts can be expensive to replace, with idler and driving screws needed to be replaced as one to ensure parts intermesh without issue and efficiency is maintained.

Screw pump is a part of the dry compressed gas transfer pump series. They are positive displacement pumps that use one or more screws to move fluid or water along the screw shaft. These screws interlock to pressurize the fluid and move it into the system. These screws engage each other and reciprocate in the cavity of the cylinder. They are often used in industrial vacuum applications, often in combination with Roots blowers, and as oil-free roughing pumps in high vacuum and ultra-high vacuum systems. Please check out the description of various pumps

Screw pump operates with two counter-rotating screw rotors that are carefully designed to rotate “toward each other”. This traps the gas in the space between the rotor “screws”. As the screws rotate, this trapped volume is reduced, which not only compresses the gas, but also moves it toward the exhaust port.

When the progressive cavity pump begins to operate, power is supplied to the drive screw via an electric motor. The drive shaft is connected to the screwdriver that drives the screwdriver.

When the drive screw starts to rotate, the driven screws also rotate, as these screws engage each other. Due to the movement of these screws, a minimum vacuum starts to be generated in the inlet section. Due to this vacuum, fluid is drawn into the pump through the inlet valve.

As the fluid enters the pump, it becomes trapped between the gaps in the “screws”. This trapped fluid also moves with the rotation of the screw. As the screw moves, the volume of the trapped fluid decreases and the pressure of the fluid increases.

When a screw pump pumps oil or other types of viscous fluids, the screw surfaces are lubricated as the fluid is pumped, so there is little or no clearance between the screws.

However, when pumping gas/water mixtures, water, or other types of light liquids, these components cannot come into contact with each other. If there is no contact, the parts will wear out quickly. Therefore, do not use a triple screw pump (where one screw drives the other two without gears) for water supply or multi-phase operation.

Screw pumps have become the standard solution for almost all industrial vacuum processes. Vacuum furnaces for brazing or sintering, metallurgical systems, and even steel degassing equipment have the advantage of dustproofing and long service intervals. In food processing, food drying, food packaging and even freeze dryers tend to use oil-free progressive cavity pumps to avoid contamination of the pump oil with water or process debris. Large-scale coating like architectural glass coating machine use screw pump as a high vacuum pump rough pumping. Screw pumps are also ideal for regeneration of large cryogenic pumps.

A screw pump is made up of various components such as; a casing, a screw (depending on the type of screw pump; it can contain 1 screw up to 5 screws), bearings, a seal, a motor adapter and a drive shaft. Screw pumps are quite simple in construction.

The screw pump, as the name implies, the form of the screw is similar to a screw thread and hence by rotating it, the fluid moves along the screw thread from the suction side to the discharge side of the pump. Due to very close clearances inside the pump, the volumetric efficiency is high especially with viscous fluids as this reduces the amount of slippage of the fluid from the high pressure to the low pressure side. The pump itself like any positive displacement pump does not produce pressure, it only moves fluid but it is the actual system which produces back pressure due to friction loss.

Screw pumps are mostly used on fluids of a higher viscosity, moving these fluids with screw pumps results in energy efficient and a relatively compact machine when compared to other pump types i.e centrifugal pump. For screw pumps with more than 2 screws, they are normally used on lubricating fluids only because the screws are not geared together and are relying on the fluid to lubricate the screws.

With a twin screw pump, the screws are geared which prevent the screws contacting each other and can therefore be used on non-lubricating fluids, chemicals and food-stuffs etc Twin screw pumps are capable of a higher flow rate than higher screw pump types i.e more than 2 screws.

There are various types of a screw pump depending on the number of screws – 1 screw up to 5 screw variations with the 2 screw pump (also called the twin screw pump) being the most common where the gears must be together to prevent contact. The twin screw pump can be fairly forgiving in terms of being able to handle entrained air or gas, including slugs of gas, whereas the 3 screw pumps cannot be used in this instance as there is a real chance that the screw would touch together.

When there is more than 1 screw involved, it is often referred to a Multi screw pump. The construction is relatively simple and is capable of a higher flow rate. They can also be used in self-priming applications with the correct suction piping configuration.

Screw pumps are capable of much higher flows and pressures compared to gear pumps.  Gear pumps limit are 250m3/hr up to 16 bar whereas a twin screw pumps limit is 500m3/hr up to 16 bar and a 4 screw pumps limit is 1500m3/hr up to 80 bar. Gear pumps work by intermeshing gears with external or internal type.

As gear pumps are virutally “single stage positive displacement” pumps  with less pressure capability than screw pumps. Screw pumps have a longer screw where the pressure is divided along the length of the screw. A twin screw pump has a much greater ability of handling solids whereas a gear pump is restricted to clean fluids.

Screw pumps delivers a known quantity of fluid for every revolution whereas the Centrifugal pump is dependent on the system conditions which in turn may affect the flow rate. Due to the volumetric efficiency of screw pumps, they will usually require less energy i.e. smaller motor when compared to a centrifugal pump on the same application.

Screw pumps depend heavily on the close internal clearances being maintained t o remain efficient. There is no clearance adjustment facility on screw pumps whereas Centrifugal process pumps will usually have an impeller adjustment facility so it can restore the running clearance. Screw pump parts are inherently self-priming whereas Centrifugal pumps would require a priming system, foot valve or self-priming casing design.

Screw pumps get their name from the two or three displacing elements, which rotate against one another and have a form similar to the shape of a spindle screw. These self-priming pumps are also called screw pumps, screw compressors or spiral plunger pumps.

The spindle screws rotate against one another in the pump casing. Only one of the spindles is driven. It transfers the torque via a thin hydrodynamic film to one or several rotating, interlocked spindles. Screw pumps that handle non-lubricating liquids or liquids that contain solids require an additional drive that synchronizes the spindles with one another.

Since the spindles are shaped regularly and in the form of a thread, they interlock as gears do. The hollow spaces created are also called cavities; these serve to convey the liquids to be pumped: When the spindles turn, they move the fluid handled within the chambers from the suction side to the pressure side.

The design of screws and casing, which are matched to one another, ensures a hydraulic balance of the high axial and radial forces that occur as well as the long service life of the pump. Handling works in both directions: With the simple reversing of the drive, the handling path can be changed. Depending on the application, there is another advantage: Screw pumps work very quietly.

Spindle screw pumps feature a simple construction that offers high reliability, performance and efficiency for liquid cooling systems. Comprised of a single rotor element that is powered, while two others are idle, spindle screw pumps move fluid axially without turbulence, eliminating foaming that would otherwise occur in viscous fluids. The idle rotors are rotated by liquid pressure, essentially generating a fluid bearing, or hydrodynamic film, that provides radial support similar to journal bearings.

Spindle screw pumps move fluids of higher viscosity without losing flow rate, and pressure changes have little impact on spindle screw pumps This is important in a rotating application, such as a CT gantry system used in a CT scanner, as the pump is able to maintain constant flow and pressure while under high stress caused by high g-forces.

One of the most critical components in a liquid cooling system is the pump. Pumps are in constant operation when the unit is turned on and typically have the shortest mean time between failure (MTBF) of all components due to friction wear of bearings, pump blades and seals. If poorly chosen, the pump will fail prematurely and the liquid cooling system will fail and cause the end instrument to stop working. This can be a problem for expensive medical, laser or semiconductor equipment where hundreds of thousands of dollars could be lost per day. Compared to centrifugal pumps, spindle screw pumps provide higher reliability, performance and efficiency for liquid cooling systems.

Many different types of pumps are available for liquid cooling systems, which can make it difficult choosing the appropriate pump. Each configuration has its own advantage and disadvantage when compared to each another. Positive-displacement pumps like gear pumps, rotary pumps, vane pumps or centrifugal pumps are the most common types of pumps available for medical, industrial laser or semiconductor use. They are cost-effective but can have shorter operating lifetimes and tend to be noisier. Typical operating life is about 9,000 hours.

Designing a liquid cooling system requires specifying the pump head and motor, which is typically sold separately for larger flow rates. Pump performance can be impacted by the motor size, as a poor performing pump head will require a stronger motor. As a result, the motor will be larger, heavier, louder and consume more power than necessary. Another problem that arises from this is the additional heat generated by the larger motor will transfer to the pump and coolant. This will drop the cooling capacity and make the liquid cooling system work harder to compensate for the additional heat transfer losses. Most motors run on AC power due the lower cost of eliminating a universal power supply. Single-phase AC motors are well established and are typically cheaper than three phase AC motors, but are also bigger and less efficient.

Internal mechanical components limit the pump’s operating lifetime because of friction wear. Customers have to replace the pump after reaching a defined MTBF, which is typically 12K hours. This will result in higher service and maintenance costs which are often over looked at time of purchase.

To get the best performance in terms of pressure and flow rate, the tolerances of the mechanical components have to be very precise. For example, the gear pump is a high precision machine with extremely tight fits and tolerances. At a minimum, metal to metal contact is a given for moving parts inside the pump. This can create problems of high friction and abrasion. To reduce friction wear particles contained inside the coolant require a low mesh strainer. This will prevent large particle sizes from entering the narrow clearance tolerances and damage the mechanical components inside the pump. Cavitation, the sudden formation of low pressure bubbles, can also reduce lifetime, generate higher noise and lower pressure drop.

Most pump types do not self-prime, i.e. push coolant through pump from initial start without being gravity fed by coolant. Therefore, the pump needs to be located below the tank reservoir. Most pump types also pulsate when pushing coolant through a liquid circuit, which can be unusable for higher end applications. Pulsations will cause disturbances to maintaining peak performance and also increases vibration, which reduces operational life of a high-end system. To get the best performance and efficiency of a pump, tight tolerances of internal moving parts are required. The tighter the tolerance the better the performance, but this also increases noise and motor performance requirements due to the increase in friction. The tighter clearance of the working parts inside a gear pump are what enable it to efficiently pump coolants in high pressure environments. Low viscosity coolants such as water with glycol or other solvents have more of a tendency to “slip” through these tight clearances due to the higher-pressure discharge side of the pump back to the lower-pressure suction side of the pump. The phenomenon of slip causes a reduction in flow rate and pump efficiency.

Slip is a characteristic of positive displacement pumps and is defined as the quantity of fluid that leaks through internal clearances of a pump per unit of time. It is dependent upon the internal clearances, the differential pressure, the characteristics of the fluid handled, and, in some cases, the speed.

Vane pumps or centrifugal pumps have problems with cavitation. Based on mechanical design, cavitation causes higher noise level and reduced flow rates and operation lifetime. To compensate for this, a separate bypass coolant circuit is required, which results in cause higher costs and assembly.

A screw pump is a positive displacement pump that uses one or several screws to move material along the screw(s) axis. In its simplest form, a single screw rotates in a cylindrical cavity, thereby moving liquids and/or solids along the screw"s spindle. The screw pump is an old technique typically used in lower tech applications, such as irrigation systems and in agricultural machinery for transporting grain and other solids.

Spindle screw pumps also have a simple construction. A three-screw pump, for example, features a single rotor element that is powered, while two others are idle. The idle rotors are rotated by liquid pressure, essentially generating a fluid bearing, or hydrodynamic film, that provides radial support similar to journal bearings. Symmetrical pressure loading on the power rotor eliminates the need for radial bearings to absorb radial forces.

The pump head and motor are combined into one waterproof housing unit and can push either oil or water coolant. The fluid delivered by a screw pump does not rotate, but moves linearly. The rotors work like endless pistons, which continuously move forward. Flow through a screw pump is axial and in the direction of the power rotor. The inlet hydraulic coolant that surrounds the spindles is trapped as the spindles rotate. The coolant is pushed uniformly with the rotation of the spindles along the axis and is forced out the other end. Due to this the power consumption is reduced, higher efficiency is achieved and the overall motor size can be reduced. This also enables the spindle screw pump to move fluids of higher viscosity without losing flow rate, and pressure changes have little impact on spindle screw pumps This is important in a rotating application, such as a CT gantry system used in a CT scanner, as the pump is able to maintain constant flow and pressure while under high stress caused by high g-forces.

Long life operation is built into the spindle screw design due to no metal-to-metal contact between moving components. This minimizes friction wear and abrasions that can cause cavitation. The flexible mechanical assembly allows the use of a smaller strainer with higher mesh size that extends maintenance intervals and reduces the overall cost of ownership. No metal-to-metal contact also results in the elimination of pulsations, even at high flow rates, making the unit very quiet during operation. The end result is smooth and quiet operation even at high revolution rates and pressure.

Spindle screw technology is ideally suited for liquid cooling systems in environments that require low noise conditions, such as imaging systems for patient modeling.

Self-priming spindle screw pumps allow an independent flexible positioning within the liquid cooling system. Respective to the cost of ownership the value of highly reliable spindle screw pump is thru high lifetime operation that can span over several years with minimal to no maintenance. This minimizes down time by eliminating the need to turn off the end user system for pump replacement.

Compared to centrifugal pumps, spindle screw pumps offer many advantages including moving fluid axially without turbulence, which eliminates foaming that would otherwise occur in viscous fluids. Spindle screw pumps are also able to pump fluids of higher viscosity without losing flow rate. In addition, pressure changes have little impact on spindle screw pumps, making them ideal for a wide range of applications. Spindle screw pumps provide more consistent, reliable and efficient performance in liquid cooling systems.
