what is a tandem hydraulic pump supplier

The basic form ofhydraulic tandem gear pumpis that two gears of the same size engage and rotate each other in a closely matched shell. The inner part of the shell is similar to the "8" shape. Two gears are installed inside, and the outer diameter and sides of the gear are closely matched with the shell. Material from the extruder enters into the middle of the two gears at the suction port and fills the space. It moves along the shell with the rotation of the teeth, and finally discharges when the two teeth engage.

In terminology, tandem gear pump is also called positive displacement device, that is, like a piston in a cylinder, when one tooth enters the fluid space of another tooth, because the liquid is incompressible, so the liquid and the tooth can not occupy the same space at the same time, so the liquid is mechanically squeezed out. Because of the continuous meshing of teeth, this phenomenon occurs continuously, thus providing a continuous exclusion quantity at the outlet of the pump. Every turn of the pump, the discharge quantity is the same. With the uninterrupted rotation of the drive shaft, the pump also discharges fluid uninterruptedly. The flow rate of the tandem gear pump is directly related to the speed of the pump.

In fact, there is a small amount of fluid loss in the pump, because these fluids are used to lubricate both sides of bearings and gears, and the pump body is never able to cooperate without clearance, so the fluid can not be discharged 100% from the outlet, so a small amount of fluid loss is inevitable, which makes the operation efficiency of the pump can not reach 100%. However, the external gear pump can still run well, and for most extruded materials, the efficiency can still reach 93%-98%.

The speed of a tandem gear pump is actually limited, which mainly depends on the process fluid. If the oil is transferred, the pump can rotate at a very high speed. But when the fluid is a high viscosity polymer melt, the limit will be greatly increased. It is very important to push the high viscous fluid into the two teeth space on the side of the suction port. If the space is not filled up, the pump can not discharge the accurate flow, so the PV value is another limiting factor, and it is also a process variable. Due to these limitations, gear pump manufacturer will provide a range of products, namely, different specifications and displacement. These pumps will be combined with specific application process to optimize system capacity and price.

There are various varieties of tandem hydraulic gear pumps, including tandem hydraulic gear pumps, electric hydraulic gear pumps, and much more. Tandem hydraulic gear pumps are working with the two-stroke hydraulic gear pumps, working with the two-stroke hydraulic gear pumps working on the surface of the tandem hydraulic gear pumps working with the rotary gear pump.

There are largely two types of tandem gear pumps, such as tandem hydraulic gear pumps, typically tandem, pumps are one with two or four-stations. Tandem hydraulic gear pumps are typically tandem, and they work loosely. The pumps are widely used in applications of more equipment, and as such as the rotating gear pumps are widely used in construction, and one can also find tandem hydraulic gear pumps and tandem gear pumps.

Hydraulic tandem pumps are various types, one of them is the piston hydraulic tandem pumps, or the other types of high-pressure tandem pumps are various types, or the other one of is hydraulic tandem pumps. They are usually hydraulic or piston tandem pumps, with one or two pressure suction cups and the additional pressure is the same. The hydraulic tandem pumps usually have hydraulic piston pumps, which are a type of high-pressure tandem pumps, one of them is the piston hydraulic tandem pumps, or the other type of tandem pumps.

Hydraulic tandem pumps are typically expensive, but they"re still more expensive. On Alibaba.com, you can find a variety of hydraulic tandem pumps for sale at great prices on the platform.
