For high pressure machinery equipment, the use of conventional pumps such as gear pumps and vane pumps can hardly meet the performance of the equipment. This is also the reason why today most of the small to large hydraulic systems often use piston pumps. Today, Hitachi Filter Press Company would like to send to customers one of the models that are especially loved by customers in Vietnam, which is Piston pump model HYB85.

The piston pump always acts as the heart of the system. Therefore, it is also known as the heart of that system, if the central system works effectively, the other parts will also operate at their best capacity. The piston pump is responsible for performing the function of sucking the material supplied from the storage tank. Therefore, the supply of materials for equipment will ensure that the system operates stably and with high efficiency.

Today’s piston pump is not too difficult to find on the market, but investors also need to learn carefully to be able to buy the right high-quality machine.


Piston pump works based on the principle: Change the volume. That is, the process of sucking hydraulic fluid or pushing the fluid depends on the change of the working volume in the pump. It is made possible by reciprocating pistons inside the cylinder. The motor will be connected to the pump shaft.

In the pump compartment there will be pistons. The tip of the piston will rest on the inclined disc. When the engine rotates, the pump shaft rotates and pulls the pistons to rotate. At this time, the inclined disc will tilt at a fixed angle, causing the piston to reciprocate in the pump chamber. At the first half revolution, the pistons will move to create gaps that reduce pressure and draw inflow. The other half turn, the piston moves to reduce the pump volume, the hydraulic oil will be forced out. If the user wants to change the flow of the pump, just adjust the tilt angle of the tilt disc, very simple.


  • Built-in mechanical shock absorber and explosion-proof, safe to use
  • Save energy when operating, no high pressure overflow, reduce energy loss significantly.
  • Pump is made of special anti-corrosion material
  • Automatically prevent undervoltage, overvoltage, overload, short circuit, phase loss
  • Smooth operation, easy maintenance, low maintenance cost
  • Unskilled operator, remote pump control allows greater control over other pumps


The pump is wear-resistant

With the design of Piston fired with aluminum porcelain, after fine grinding, the HLC hardness 8.5 or higher, the surface roughness is 0.4um. The plunger will not break the characteristics of the slurry, suitable for conveying slurry containing sand and solid particles.

Pump with high pressure

Piston and vacuum pump distance, lift 0-6m (but mud characteristics will also affect lift)

Constantly adjustable Sludge pressure and oil flow automatically change

The pump working pressure can be adjusted in the range of 0-20 kg. The adjusted pressure will not be changed due to the change of pump discharge rate, it will be maintained, unaltered even if its sludge discharge is interrupted while the pump is running. (The flow variation should not exceed the maximum throughput, but the flow may be zero).

High pressure and high efficiency

The maximum pressure of the conventional model is 20 kg. At the same pressure (≥ 5 kg) and the same flow, this piston pump motor power is 1 to 2 models smaller than other pumps

Easy operation

Tighten or loosen the pressure regulating valve to adjust the pressure, then lock tight, no need to adjust in the future.

Low cost of use

The parts that are easy to wear out are the valve plate and the water seal. Normally, their replacement time is 3-6 months, for urban sludge, their replacement time is longer from 6-12 months.

Piston pump life

Piston pump has a very long life, more than 15 years
