Different types of pumps

1. Gear pump

2. Vane pump

3. Piston pump

 

1. Gear pump

 

Gear-Pump

A gear pump is used in many hydraulic systems because of the simple design and widespread availability. It has only few moving parts, works smoothly, and operates very well at pressures around 210 bar. In a gear pump, the displacement chambers are formed between the housing of the hydraulic pump and the rotating gear wheel (or gear wheels, depending on model or hydraulic pump design). Gear pumps are hydraulic pumps that are available in many different types.

2. Vane pump

Vane pumps are hydraulic pumps that operate at very low noise levels. Hydraulic vane pumps operate with much lower flow pulsation, i.e. constant flow. As such, vane pumps produce less noise while maintaining a relatively high speed of up to 3,000 rpm. Small hydraulic vane pumps like the Parker Denison T7A or T7B, with higher displacement volume of 50 cc, have a maximum speed of 3,600 rpm at hydraulic system pressures of up to 300 bar intermittent.

Vane pumps are hydraulic pumps that operate with much lower flow pulsation to reduce noise levels.

The hydraulic vane pump finds its use in die casting and injection moulding machines in industry, as well as in land and road construction machinery. The operating pressure of vane pumps does normally not exceed 180-210 bar. However, in specially designed vane pumps the operating pressure may go well over 200 bar and up to 300 bar. Parker Hannifin has Denison Vane Technology to provide us with the best solution in the market of fixed displacement balanced vane pumps.

3. Piston pump

Hydraulic piston pumps can handle large flows at high hydraulic system pressures. The piston pump is a hydraulic pump that delivers optimum efficiency and reliability while maintaining a compact size with a high power density. In these pumps, the pistons accurately slide back and forth inside the cylinders that are part of the hydraulic pump. The sealing properties of the pistons are excellent which makes it possible to operate at high pressures with low fluid leakage.
