GE Surface Pumps designed and engineered an economical SPS™ surface pumping system to replace the PD pumps. Two SPS units were supplied by GE’s Texas-Oklahoma distributor, Best Pump-Works. The model TJ-7500, 64-stage tandem SPS units with 400 HP motors (producing 250 GPM @ 1842 PSIG) were commissioned in 2008.
The SPS units feature easily replaceable multi-stage horizontal centrifugal pump elements. The units are designed for improved abrasion resistance, reduced wear and higher efficiency. They feature a single mechanical seal that operates at suction pressure. The bearing frame/thrust chamber is supplied as a replaceable module and is interchangeable with other SPS units.
The thrust chambers feature:
– very low number of rotating parts for long, trouble-free life
– simple operation and minimal maintenance (quarterly lubrication change)
– an oil-ring lubrication system for optimum oil dispersion and reduced operating temperatures
– a thermocouple to provide periodic or permanent temperature monitoring/ shut-down protection
