Prototype ZHSM hydraulic units can be used to supply water at high pressure spray systems, cooling of equipment, prophylactic rock irrigation or deep water drilling processes.

The components of aggregates are, among others: plunger water pump, SM hydraulic motor, regulating valve, filter, safety valve and shut-off valve.

The plunger water pump is driven by a SM hydraulic motor in a special arrangement that allows him to run on low-percentage-oil emulsion, hydraulic oil and other hydraulic fluids. Pump performance depends on the speed of the hydraulic motor drive. The motor speed, in turn, depend on the size and amount of pressure medium to be delivered, which can be adjusted by the control valve setting.
