Split Cylinder/Braket The packing cylinder can be readily removed, thus giving easy accessibility to all replacement wear parts. Packing and plunger changes require minimal down time.
Fluid Cylinder Body Machined from high quality solid block alloy or stainless steel, ground to precision for maximum pump performance.
Discharge and Suction Valve Assemblies Each valve assembly is interchangeable and made from precision machine ground, hardened 17-4 PH stainless steel. No wing guide or threads are required, reducing field maintenance and increasing pump efficiencies. Features a reversible seat in hardened stainless steel. Balls are highly polished, ground and hardened stainless steel. All o-ring seals are flat surface designed, which reduces o-ring cutting and provides maximum pressure sealing.
Power Plungers The power plunger is heat-treated stainless steel ground and polished to an 8 rms surface finish for extended packing life.
Plunger Packing Multiple element Chevron style packing is used and is self adjusting, requiring minimal field maintenance. Packing lubrication is achieved with gravity oil drip or grease injection.
Direct Drive Quiet running pinion and main gears are helical cut and machined from high stregth alloy steel, and can rotate in either direction. The internal gear reduction allows for direct drive coupling to most power sources.
Crankcase Oilfield rugged cast iron case protects internal components and the upper half of the case is easily removed for inspection and service.
Automotive Type Crankshaft Forged from alloy steel and balanced for continuous duty operations.
Shaft Bearings Precision conical tapered roller bearings support each shaft end.
Crankshaft Journal Bearings Journal bearings are high quality automotive type steel- backed inserts.
Connecting Links Links are SG Iron with replaceable wrist-pin bushings.
Crossheads Heavy duty iron crossheads eliminate side loads on power plungers.
Pony Rods Rods are smoothly ground and highly polished stainless steel, threaded and pinned to align perfectly with the cross head and power plunger.
Continuous Splash Lubrication Oil in the crankcase reservoir is picked up by the main helical gear and spread to all moving parts. Forced feed lubrication available on request.
