The plunger pumps, designed and produced to produce smooth operation in continuous cycle mode, are reliable, low maintenance resolution aimed to provide longwall with hydraulic power. 

The robust pump unit serves to quiet continuous operation with the best performance wherever the pump unit is placed – in a longwall or at the pump station. Typically the team is skid-mounted on the subframe of the flange-mounted prime mover or support-mounted. 

The pump plungers are actuated by the forged rotating shaft supported by spherical roller bearings; the crankshaft is driven using the double-helical wheel, which reduces the amplitude and improves efficiency. 

The compact design of the pump body ensures direct access to the suction and discharge valves with no need to dismantle the plunger or pump body, therefore providing simple maintenance. The suction and discharge valves are identical, interchangeable, and made from special steel. 

Using the complex ceramic oxide for the plunger construction reduced the wear and tear considerably and extended the life at a similar time. The plungers may be replaced at the site without any special tools. In case of an oil seal housing leak, liquid flows to the suction chamber, minimizing the fluid loss. 

Plunger pumps are also known as Piston Pumps and Triplex Plunger Pumps
