Grundfos 7S05-11 (31595115) Submersible Deep Well Pump 1/2 HP, 230V, 4" MTR, 1" NPT, 2-wire, 1 PH, 15.2" Pump End, 11 Stages

Grundfos 7S05-11 (31595115) is a 1/2 HP 230V Submersible Multistage Well Pump with 4" Motor and 15.2" Pump End - made for 4" and larger wells or boreholes, ideal for raw water supply, groundwater lowering and pressure boosting, suitable for pumping clean, thin, non-aggressive liquids without solid particles or fibers and designed for residential, commercial, industrial and agricultural applications.

Grundfos Well Pump can be used in closed and open automatic water systems with different type of installation components and configuration. Standard installation requires check valves (recommended every 100'), torque arrestor, pressure switch and should include typical accessories such as lightning arrestor, expansion tank, pressure controls, gate valve, relief valve and tank valve drain - all are sold separately (see included PDF files). Additionally, enhanced protection capability and closer data monitoring can be provided by MP 204 motor protection unit with R 100 remote control.

Grundfos Submersible Pump features 1" NPT discharge with head capacity of 310', specifically engineered for both continuous and intermittent operation. The Water Well Pump is suitable for horizontal and vertical installation with maximum 104F liquid temperature operation. Grundfos Submersible Well Pump is made entirely of high-grade corrosion-resistant stainless steel with patented Splined Shaft Construction which is designed to provide years of trouble-free performance. Built-in Radial Thrust Top Bearing provides sand protection and allows the water well pump to handle the sandy conditions often found in domestic wells. The Water Well Pump is fitted with a built-in jam-free Check Valve prevents back-flow into the well once the pump is shut down and Upthrust protection guarantee smooth running with fail-safe operation. Over temperature protection is provided with bi-metallic overloads. Specially designed Michell Type Carbon/Ceramic Thrust Bearing with heavy-duty 900 lb. thrust capacity, exceeds NEMA ratings. A user friendly cable guard aids in ease of installation. Grundfos 7S05-11 Submersible Well Pump is retrofitted with Nitrile Rubber and Valox PBT to handle the rigors of contaminated groundwater pumping with long-lasting reliability.

Powerful, permanent split capacitor (PSC), 1/2 HP single phase MS 402 Motor (3450 RPM) delivers 7 GPM at 210', built to deliver optimum efficiency, incorporating motor protection and a starter device, thus allowing the Pump to be connected directly to the mains. The Motor fill fluid (SML2) provides bearing lubrication, protects the motor from freezing down to 4F, prevents the growth of bacteria and requires no additional lubrication. Grundfos Water Well Pump boasts rugged and durable 304 Series stainless steel construction for all vital pump components including impellers, diffuser, shaft, guide vanes, coupling and hardware. Computer-aided design and manufacturing techniques of the patented 11 Stage Pump End and Motor ensure that the Well Pump is built to exacting tolerance and perform to industry-leading standards. Highly advanced design and manufacturing techniques minimize the number of moving parts with each component designed for ultimate hydraulic efficiency. Grundfos 7S05-11 Submersible Stainless Steel Well Pump is built for heavy-duty performance with maximum efficiency and reliability.
