Features
◆ Stainless steel construction designed and built for years of trouble free operation
◆ Designed and built to operate in difficult conditions.
◆ All metal parts are made of 304 or 316 stainless steel, except for the shafts, which are made of 431 or 316 stainless steel.
◆ Heavy duty stainless steel discharge head with built-in check valve for preventing back flow in connection with pump stoppage and the risk of destructive water hammer is reduced to a minimum.
◆ NEMA standard of bracket mounting.
◆ High quality shaft bearings provide low friction and high wear resistance.
◆ The stop ring prevents damage to the pump during transport and in case of up-thrust in connection with start-up. The stop ring, which is designed as a thrust bearing, limits axial movements of the pump shaft.
◆ Stainless steel strainer to restrict the entry of sand and other extraneous material.
