46 4’’WPS® P 4”WPS® P pumps are constructed out of stainless steel AISI304 and are equipped with Noryl® floating impellers and polycarbonate diffusor parts. Pumps are suitable for both continuous and intermittent operation for a variety of applications: • Domestic and general water supply • Irrigation • Tank applications • Pressure boosting Note: for other applications, please contact Well Pumps. 4”WPS® P 4”WPS® P pumps offer the following features: • Discharge chamber and Suction Interconnector are precision casted in stainless steel AISI 304. • Motor adaptor following NEMA standard. • Impellers are floating type and made out of Noryl®. This in combination with glass fiber polycarbonate diffusors parts leads to a strong pump with an good resistance against abrasion. Maximum sand content 300 g/m3 • The bowl part of the diffusor is produced out of stainless steel AISI 304. • Shaft and coupling are constructed out of stainless steel AISI 304. • Stainless steel AISI 304 non-return valve cone. • Top Bearing is produced out of Polyacetal with strong resistance to wear and abrasion. • Strong Pump Sleeve of 1.5mm thick out of stainless steel AISI 304. • Strainer produced of stamped AISI304 stainless steel. • Suitable for drinking water applications: ACS and FDA-certified. Pump and motor range 4”WPS® P pump range consists of nine flow models: 1, 2, 3, 4, 6, 8, 10, 12 and 16 m³/h. Pumps are mounted on 4”WPS® encapsulated water-filled submersible motors with all parts in contact with water made out of stainless steel AISI 304. Power range from 0,37 up to 2,2 kW in single phase and up to 7,5 kW in three phase supply. Pipe connection 4”WPS® P pumps with flow of 1, 2 and 3 m³/h have a Rp 1 ¼” outlet. The 4”WPS® 4 P pump has an outlet of Rp 1 ½” and pumps with flow range of 6m³/h and higher has a Rp 2” outlet. Pump identification code Example 4” WPS® 4 – 12 P Curve conditions • Curve tolerances according to ISO 9906:2012, class 3B. • The performance curves show pump performance at actual speed of the standard motor range. • The measurements were made with airless water at a temperature of 20°C and a kinematic viscosity of 1 mm²/s. For pumping liquids with a higher density than clear water, motors must be used with correspondingly higher outputs. • Q/H: the curves are inclusive a valve and inlet losses at actual speed. • Power curve: P2 shows pump input power at the actual speed for each individual pump size. • Efficiency curve: η shows pump efficiency.
