125 SERIES PUMPS

The 125 pump is available with either an internally or non-internally geared power end.  (Click on the links to view the brochure for the version you are interested in.)

Fluid End Features Include:

Easily configured for operating pressures from 6 000 to 40 000 psi in under 20 minutes.

A single stainless steel frame plate and swing-out manifold is used for all operating pressures.

The design features minimum volumetric clearance and stress, with maximum shock and pressure resistance.

Passages are drilled to minimize turbulence.

The valve seat and stuffing boxes are precision-machined from high-grade stainless steel.

Stainless steel valves have a rugged, double guided design that improves valve life by ensuring alignment. Seats are beveled and are also made from hardened stainless steel.

Pump features Colomony®-coated plungers for 6-10K operation and solid tungsten carbide plungers for 15-40K operation.

Power Frame Features include:

Horizontal configuration provides easy access and low center of gravity.

Rugged, cast-iron housing with gravity lubrication and large oil reservoir.

Forged steel crankshaft mounted in heavy duty bearings.

Drive pinion output shafts on both sides of pump allow for opposite-hand drive. (G Version)

Internal gearing eliminates the need for large pulleys or belts, greatly decreasing the pump’s overall footprint.  (G version)

Large-diameter cylinder crossheads operating in full circular guides, fitted with hardened wrist pins.

Ground crosshead stub shafts with lipped seals to keep water and dust out of crankcase.

High mechanical efficiency.

Plunger cover for cleanliness and operator protection.
