The plunger pumps, designed and produced to provide smooth operation in continuous cycle mode, are reliable, low maintenance solution aimed to supply longwall with hydraulic power.
The robust pump unit serves to noiseless continuous operation with the optimal performance no matter where the pump unit is placed – in a longwall or at the pump station. Usually the unit is skid-mounted on sub frame of the prime mover which is flange-mounted or support-mounted as well.
The pump plungers are actuated by the forged crankshaft supported by spherical roller bearings; the crankshaft is driven by means of the double helical wheel which reduces the noise level and improves the efficiency.
The compact design of the pump body ensures the direct access to the suction and discharge valves with no need to dismantle the plunger or pump body, thus providing easy maintenance. The suction and discharge valves are identical and interchangeable, and made of special steel.
The use of the hard ceramic oxide for the plunger construction allowed reducing the wear greatly and, at the same time, extending the life. The plungers can be replaced at site without any special tools. In case of oil-seal housing leakage liquid flows to the suction chamber, thus minimizing the liquid loss.
Main pump advantages:
The product range includes the plunger pumps and package high-pressure systems as well including associated accessories for all the applications with drive power up to 1200 kW.
Some pump capacity reaches 2400 l/min (at 95 bar) for fresh water, demineralized water, emulsions and light oils, etc.
Water pressure is up to 2500 bar (at 40 l/min).
Special edition of pumps are manufactured for the application in subsurface mining works as well as for sea-water desalting plant (reverse osmosis).
