When you consider which high-pressure electric pump is right for an application, there’s a lot of emphasis on getting the proper flow and pressure. And rightly so. Determining proper GPM and PSI is critically important.

Performance is generally determined by the amount of horsepower in electric motors. What is the role of horsepower and how can you determine how much you need?

The term horsepower, often abbreviated HP, stems from the 18th century and was coined by Scottish engineer, James Watt. He developed a calculation that compared the power of draft horses to the output of steam engines which were relatively new technologies at the time. Today, horsepower units are used to measure the output power of numerous types of engines or motors. The electrical equivalent of one horsepower is 746 watts.

So, what’s the significance of horsepower? In vehicles, the more horsepower an engine has, the more towing capacity or speed it can deliver. If you want to increase performance in either regard, you’ll need to increase horsepower.

The same principle applies to pump motors. If you have a pump rated at 6 GPM and 1,000 PSI and you want to increase its performance, you’ll need to use a more powerful motor. Even so, a pump sprayer with a certain GPM and PSI rating won’t necessarily produce those numbers if the motor isn’t powerful enough or efficient enough. Trying to get more output out of a pump than it’s rated for without increasing the motor size will likely cause it to stall, overheat, and fail.

A pump’s motor ratings are more often referred to in amps rather than horsepower. A 30 amp pump is equivalent to about ¼ HP. So, the more horsepower a motor has, the more amps it will draw. When working with battery-powered pump systems, amperage draw becomes a big concern.

Drawing too many amps will drain batteries quickly. Most operators want to get through an entire day on a single charge rather than swapping out batteries multiple times each day or waiting to recharge.

That’s why it’s important to pay attention to efficiency ratings on the pumps you choose for an application, as that can tell you how many amps you’re really getting. Centrifugal pumps, for example, may have efficiency ratings as low as 50%. By comparison, Pumptec plunger pumps are rated at 93% efficiency. Why does it matter?

Take, for example, a 30 amp Pumptec plunger pump (¼ HP). At 93% efficiency, you’re getting near maximum performance. If you only get 50% efficiency from a centrifugal pump, you’re only able to use 15 of those amps, or ⅛ HP. In a 50 amp motor — equivalent to ½ HP — you’d only use 25 amps or ¼ HP. The rest is going to waste.

To get similar performance ratings in a centrifugal pump as with the plunger pump, you’d have to nearly double your amperage and horsepower, meaning a bigger, less mobile pump system at a higher price tag. Even if a pump operates at 80% efficiency, that means you’re still losing one-fifth of its potential power and would have to use a larger (and more expensive) pump motor to make up for it.

Some types ofpositive displacementpumps are more efficient because of their simpler drive mechanism. While centrifugal pumps also have a simple drive and few moving parts, they are less efficient due to hydraulic friction. After the pump has run for a period of time, the impeller wears, the hydraulic loss is increased, and the hydraulic efficiency is lowered. Triplex oil bath pumps are less efficient due to lots of moving parts working against the resistance of the oil. The nature of a Pumptec sealed bearing plunger pump’s design is inherently more efficient.

Some pump operators believe they need a more powerful pump; that if it just had more horsepower, they’d be able to get in and out of jobs faster and get better performance.

Many pump operators purchase pumps that are actually oversized for the job. You might purchase an off-the-shelf 1.5 GPM pump but only use 1.3 GPM, meaning .2 GPM ends up going through bypass. That’s very inefficient. Ideally, you’d use a smaller motor at a lower price point and get better performance. Plus, the smaller pump would offer more mobility and longer battery life. The good news is that pumps can be customized to meet a specific flow rate for an application.

Using a pump performance chart is one way to determine your needs. An even better way is to work with a pump engineer to pinpoint the ideal GPM and PSI for your application and then design a pump solution to your specifications. To help you get started, use our free Guide to Proper Pump GPM and PSI. It outlines common standards for several industries.

Then, reach out to our pump experts. Whether an OEM manufacturer of pump equipment or a commercial business with a team of operators, we’re happy to talk through your needs and explore solutions.

Working oil: A mineral based oil with additives to resist corrosion oxidation, & foaming is recommended. Viscosity at any running condition should be 60 SUS minimum & 250 SUS maximum. 180° F is the maximum recommended system operating temperature

If you’re a pump sprayer operator and you’re performing a soft wash application on a two-story residential home to remove lichen or mold, how do you get the spray pattern to reach the eaves of the home and provide even coverage without having to climb a ladder?

There’s a common misconception that to achieve a broader vertical or horizontal spray pattern, you simply need a pump that puts out more pressure. On the contrary, increasing the flow rate is often the key.

It’s not uncommon to hear pump operators complain that their sprayer doesn’t have enough pressure when, in fact, the issue is the flow rate. In fact, some people use the two terms interchangeably, as though they’re the same thing. They’re not, and knowing the difference and the role each plays is the key to achieving proper pump performance.

A pump’s job is not to deliver pressure; rather, it is to deliver a rate of flow, pumping a certain amount of liquid over a given amount of time from a tank or reservoir to the outlet. Flow rates are often referred to in gallons per minute or GPM. There are some smaller pumps that rate flow at gallons per hour or even gallons per day, outputting extremely small amounts of fluid over a given time.

Pump pressure, however, is a measure of resistance to flow. Without flow, there is no pressure. In a positive displacement pump, such as a plunger pump, the rating in pounds per square inch, or PSI, outlines how much resistance the pump is designed to withstand.

A pump’s PSI rating is important because it indicates that the pump was manufactured out of materials and designed to handle a certain amount of pressure. But for pump operators, they should be equally concerned with a pump’s flow rate which determines how much you want to dispense, spray, or inject.

In general, when pump pressure increases, flow will decrease. Take, for example, a misting pump that needs to produce an ultra-fine mist for cooling or dust suppression. Many misting pumps are rated at 1,000 PSI, yet their flow rate is quite low at .25 GPM.

Clearly, high pressure in this instance is very important to produce the right size droplets. However, it doesn’t indicate more output or vertical or horizontal throw. Instead, the higher pressure combined with the right nozzles results in a fine mist with very little flow that might only cover a small patio area.

On the other hand, a soft wash sprayer can be rated at a mere 100 PSI and have a GPM of 5.4, yet it can achieve a vertical throw of nearly 40 feet and a horizontal throw of more than 50 feet when paired with the proper nozzles.

More pressure changes the velocity of the fluid, but it also decreases the flow or output. The cause of the flow decrease is due to two factors: volumetric efficiency of the pump and reduced motor speed. Volumetric efficiency is a measure of the actual flow compared to expected theoretical (calculated) flow — volumetric efficiency decreases as pressure increases. Our positive displacement plunger pumps have about 90–100% volumetric efficiency compared to centrifugal pumps that range from 0–100%. This means that plunger pumps only lose about 10% of the flow when pumping against back-pressure, while centrifugal pumps will lose all the flow when pressure climbs too high.

Reduced motor speed occurs when motors are loaded heavier. So, when pressure in the pump causes more load on the motor, it slows down. When the motor slows down, the flow rate drops at the same percentage. A motor that operates at about 2000 RPM at low pressures will typically slow down to about 1750 RPM when the pump is pressurized to the maximum rating.

It stands to reason, then, that increasing pump pressure will not increase flow. In the soft wash example, more pressure won’t help the operator reach the eaves of a two-story home with the same amount of coverage. The operator needs a pump motor with an ideal combination of pressure and flow.

Engineering pumps for any application requires an understanding of fluid dynamics, and each industry has varying needs. Too often, a company will choose an off-the-shelf high-pressure pump to get a job done and wonder why it doesn’t perform as expected. It’s likely because the operators lack a full understanding of the relationship between flow and pressure.

The engineering experts at Pumptec have a thorough grasp on fluid dynamics and help OEMs and pump distributors pinpoint their exact needs. They make recommendations based on scientific principles and years of experience serving multiple industries, and can even customize pumps to your application’s precise needs.

In fact, we’ve developed a Guide to GPM and PSI that provides some of those industry recommendations. Take a look through it and then contact the pump experts at Pumptec. We’ll be happy to discuss your needs and determine the right pump for your application.

Selection of the proper pump for a particular application is dependent upon a number of factors such as: material compatibility, liquid being pumped, pump location, pump size, pump type, pump speed and horsepower. Here are some general guidelines to help you make the right choice.

Materials must be compatible with the liquid being pumped. Plastics or polymers may react differently depending on the type of solution or liquid being used. Temperature of solution is also a factor. Pacer Pumps are not ideal for agressive chemicals or high temperature processes. Internal pump parts like seals and o-rings must also be compatible with the liquid being pumped.

Our pumps are of horizontal design coupled with a variety of drivers which achieve multiple flow/pressure combinations. Different pump internals can also be used to achieve various flow and pressure combinations. Centrifugal pumps typically operate at speeds of 1725 RPM or 3450 RPM. The low RPM pump has half the flow, one fourth the pressure and requires one eighth the horsepower of the high RPM pump.

Pump ratings are based on moving a liquid with a specific gravity (SG) of 1. When specific gravities higher than 1 are encountered, oversized drivers must be utilized.

In order to achieve a desired flow and pressure, the pump selected must provide a Total Discharge Head (TDH) at the given flow which must exceed the desired discharge pressure plus friction losses resulting from the length of pipe or hose, fittings and valves in the line along with any other impediments to flow within the line.

The matrix shown below will allow you to see the various pump series and drivers that we offer. The driver is your preferred method of rotating the pump"s impeller. Close-coupled configuration is more compact and the pump is mounted directly to your specified driver. Long-coupled configurations create more separation between your pump and driver. This configuration takes up more space as it utilizes a bearing pedestal and flexible coupling between your pump and driver.

A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flows into torque and angular displacement (rotation). Hydraulic motors serve the electric power, construction, water conservancy, transportation, ships, automobiles, aerospace and military field. Hydraulic systems are widely used in papermaking, textile, plastics, rubber and other light industries. It also plays an important role in heavy industry, like mining, petroleum, metallurgy and pressure processing.

When purchasing a hydraulic motor, the main basis is requirements for the hydraulic system, such as torque, speed, working pressure, displacement, shape and connection size, volumetric efficiency, total efficiency, quality, price, supply, convenience of use and maintenance.

High power-weight ratio: The ratio of the energy transmitted by the hydraulic motor to its own weight is very small compared to other transmission methods.

According to its structure type, hydraulic motors can be divided into gear, vane, piston hydraulic motor and other types. ATO has a wild range of hydraulic motors to meet your buying requirements. Each has its specific purpose and applicable working conditions. This time, some of ATO"s bestselling hydraulic motors are presented below for you to purchase.

After determining the type of hydraulic motor, several specifications that meet the needs can be selected according to the required rotational speed and torque. First, the corresponding pressure drop, flow rate and efficiency are calculated through the characteristic curves of various specifications, and comprehensive analysis could be carried out.

If the original cost is the most important, you should choose a motor that not only meets the torque requirements, but also makes the system flow smaller and lower pressure, so that the hydraulic source, control valve and pipeline specifications can be smaller.
