Kocsis Hand Pump ( HPA-300118)



The Kocsis Hand Pump HPA-300118 is a manually operated hydraulic hand pump manufactured by Kocsis Technologies, Inc. (KTI), designed for recharging hydraulic starting systems used in industrial engines, oil & gas equipment, marine machinery, and other heavy-duty applications. The HPA-300118 provides a reliable means of restoring hydraulic system pressure without requiring an external electrical or mechanical power source.
The Kocsis HPA-300118 hydraulic hand pump is particularly suited to hydraulic engine starting systems where manual pressure regeneration is required during emergency starting or black start conditions. By operating the hand lever, personnel can manually recharge the hydraulic system to support subsequent engine starting attempts.
Featuring an aluminum housing, stainless steel piston, and cold-rolled steel handle, the HPA-300118 is designed for a maximum allowable working pressure of 3,000 psi (207 bar). The pump delivers approximately 1.22 cubic inches (19.99 cm³) of hydraulic fluid per cycle and incorporates a manual bypass relief arrangement for hydraulic system operation.
