Derrick offers a complete line of centrifugal pumps to accommodate a full variety of drilling applications. Sizes range from 2 × 3 to 6 × 8. Bare pumps, horizontal packages, and overhead belt drive configurations are available. Explosion proof electric motors are available up to 200 HP, in 1200, 1800 or 3600 RPM.
The Derrick Premium 250 pump series incorporates proven oilfield features including a heavy-duty 2-1/2” diameter shaft. Standard features include a replaceable casing wear pad, premium bearings and tungsten carbide mechanical seal. The Derrick Premium 250 pump parts are interchangeable with industry standard type pumps
Derrick’s large diameter shaft is designed with a replaceable shaft sleeve, allowing packing wear area replacement independent of the shaft. Minimal shaft deflection aids in packing or mechanical seal life. The Derrick Premium 250 replaceable casing wear pad allows worn area replacement without replacing the entire casing.
Premium bearings throughout include a double row ball-bearing inboard to accommodate large impellers. High thrust load, zero endplay angular contact bearings are utilized outboard. Grease type lubrication is standard and oil bath lubrication is also available.
Overhead belt drive packages are skidded, as shown, and include the Derrick Premium 250 pump, an explosion proof electric motor, belts and sheaves, and OSHA type belt guard. Starters are optional.
Horizontal packages are skidded, as shown, and include the Derrick Premium 250 pump, explosion proof electric motor, and coupling with OSHA type guard. Starters are optional.
Available on the website, Derrick offers a centrifugal pump-sizing calculator to assist in determining total dynamic head requirements, impeller sizing and proper line sizing. Please consult a Derrick representative for further information.
