SPM QWS 1S HD Well Service Pump Oil & Gas The SPM QWS 1S HD is designed with quick and practical maintenance in mind, while supplying 6% higher rod load at pressures of 15, utilizing a 3 plunger and 2, utilizing a 2.5 plunger. The SPM QWS 1S HD pump has been designed to eliminate contamination from pumping media into the power end, lengthening pump component life. Retrofit kits are available for customers currently operating SPM QWS 1S pumps, helping them make the transition to the SPM QWS 1S HD pump. Customers are able to update their units to the latest technology without the capital investment of a complete new unit. Design Features Increased rod load by 6%* to achieve 15 ksi rating with a 3 plunger or 2 ksi with a 2.5 plunger Eliminated fluid and proppant contamination potential in the power end greatly increasing power end seal life Removed 1 lbs (7%)* of reciprocating weight per cylinder while maintaining or improving design safety factors Improved lubrication through the use of ported crankshaft and ventilated shell bearings Reduced maintenance time by not having to remove the diaphragm seal in order to remove packing nut Contamination of the power end is also reduced* as the power end remains sealed during fluid end maintenance Knuckle bearing connecting rod design provides 7% more surface area for improved load transfer* Technology can be retrofitted into existing pumps without modification * Compared to conventional SPM QWS 1S pump Applications: Cementing, acidizing, gravel packing, snubbing Maximum Brake Horsepower Input... 1 BHP (746 kw) Maximum Rod Load Capacity...16,29lbf (472 kg) Stroke Length...6 (152.4 mm) Gear Ratio... 4.61:1 Approximate Length...5 (1,27 mm) Approximate Width... 73" (1,854 mm) Approximate Height... 24" (69 mm) Approximate Weight (Dry)... 7,4 lb (3,193 kg) Note: Pump dimensions and weights are approximate.
