Pump frames suffer from stress cracking and fatigue cracking at the front-end bulkhead and at the pinion, crankshaft, and bearing support areas, so White Star has paid particular attention to the strength of the frame and the way it's manufactured. The frame is fabricated from hot rolled plate and the longitudinal plates have been increased in thickness by nearly 1/2" to prevent the frame from "breathing". The White Star 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 of the pump. 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. The strongest frame in the industry and compatible with Ideco parts.

Crankshaft, Pinion & Bull Gear

White Star's crankshaft is manufactured from a modified 4340 material with high nickel content to reduce crack initiation and propagation. It has a high chrome content to prevent corrosion. White Star 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 our 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. Interchangeable with Ideco mud pumps.

Connecting Rods

Our connecting rods are made from high specification alloy steel. White Star connecting rods are machined with high precision to ensure the alignment between the crankshaft and the crosshead. Interchangeable with Ideco mud pumps.

Crossheads and Guides

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.
