White Star Pump Company

Frame and Skid

Pump frames suffer from stress cracking and fatigue cracking at the front-end bulkhead and at the pinion, crankshaft, and bearing support areas, so we have paid particular attention to the strength of the frame and the way it's manufactured. The material is 4140 plate and the longitudinal plates have been increased by nearly 1/2" to prevent the frame from "breathing". The pump frame is machined the full length of the hold down runners at the base on either side. The skid has a fully milled flush run of 1" plate the full length. When the pump is bolted with the machined skid the stresses from the front end of the pump are transmitted through the skid, which provides added strength to the frame and a reduction in stress at the high stress points typical of other existing triplex pumps.

Crankshaft, Pinion, Bull Gear, and Connecting Rods

The crankshaft is manufactured from a modified 4340 material with a high nickel content to reduce crack initiation and propagation. It has a high chrome content to prevent corrosion. The crankshafts are static balanced for smooth operation to reduce noise and vibration, which extends the life of the bearings and crankshaft. The Pinion and bull gear are made from similar material to the crankshaft and with a high precision double helical gear, with less backlash than any of the competitors. The precision gears ensure power is transmitted over the full width of the adjacent gears and the decreased backlash prevents the hammering effect, which occurs with speed change. The connecting rods are made from high specification Alloy Steel and machined with high precision to ensure the alignment between the crankshaft and the crosshead.

Crossheads and Guides	Ancillary Parts
White Star's crossheads are manufactured from high quality, cast steel and the guides are manufactured from a quality manganese bronze normally used in bearings. This combination of materials provides a low friction interface and generates very little heat, which indicates no friction, which equates to no wear.
Fluid End
	White Star ancillary parts are all considered critical to successful pump-operation. Whether it's a simple liner nut with a modified acme thread, a plug retainer or an extension rod, they are designed and manufactured to the highest standards.
White Star's discharge manifolds are single piece alloy steel forged then machined for maximum strength and life. The fluid end modules are in one or two-piece configurations, using quenched and forged steel material. White Star's Pulsation dampener, rated at 5,000 psi, is made from forged alloy steel. Each dampener is hydrostatically tested to 10,000 psi before shipment. White Star's dampeners are completely field serviceable, and interchangeable with leading brands. A standard replaceable bottom plate helps reduce maintenance costs when plumping abrasive or corrosive fluids. The top flange permits replacing the urethane or Buna-N (nitrile) diaphragm bladder without removing the unit from the pump.
