Summary: Flowserve Pump Specification and Proposal Document

This is a comprehensive commercial pump specification and proposal document from Flowserve dated June 17, 2026, for a 2K3x2V-10RV M3V single-stage centrifugal pump serving as a D1131 replacement unit. The pump is rated at 135.0 USgpm capacity with 69.00 ft total developed head, operating at 1,750 rpm with a 5.00 hp (3.73 kW) driver. Key specifications include an 8.38-inch impeller diameter (rated), 53.6% overall efficiency, and a required minimum Net Positive Suction Head Available (NPSHa) of 2.8 ft. The pump features carbon steel casing with 316 stainless steel impeller, ASME B73.2M specification compliance, and ISC2 Series single mechanical seal with Plan 03 flush system. Testing includes 10-minute non-witnessed hydrostatic test at 428.0 psig on casing and cover only, with no performance or NPSH testing required.

The scope of supply includes the pump with jacketed integral cover, standard Mark IIIA power end with regreasable bearings, T.B. Woods Sure-Flex SC6 coupling with steel guard, steel pump stand baseplate, and a WEG NEMA motor (TEFC-W22, SD, PE, 5.00 hp, 1,800 rpm, 184TC frame, 230/460 volts, 3-phase, 60 Hz). Material modifications encompass carbon steel casing and cover with 316 stainless shaft and impeller. Mechanical modifications include 150# FF ANSI drilling, plugged 1/2" NPT casing drain, 1/2" NPT suction and discharge taps, and ISO 1940 G6.3 impeller balancing. Documentation includes installation and operations manual in English with standard domestic packaging (6 months coverage) and 12-month start-up / 18-month shipment warranty. The proposal is valid for 30 days.
