Heat Shrink, Torque Arrestor, Cable, Pitless Adapter,Well Cap or Well Seal, Control Boxes, Check Valve, Pressure Switch, Pressure Gauges, Pressure Bladder Tanks and Relief Valve Torque Arrestor for Submersible Well PumpsTorque arrestors are clamped on the submersible well pump drop pipe and are field adjusted to hold the pump centered in the well casing. Fits 4"-8" well casings and 1 or 1-1/4 drop pipe. Bronze Pitless Adapters For Submersible PumpsBronze pitless adapters to insure long life and durability in the most aggressive well conditions. External installation nipple makes installation easy.Rubber inner & outer casing gaskets for certified & approved water tight seal from ground water contamination. Well Seals for Shallow Well Jet Pumps & Submersible Well PumpsCast iron well seal with rubber packing gland for submersible and jet pumps. Prevents contamination from surface drainage. Easy to install, just fit in casing and tighten bolts. Corrosion resistant zinc plated steel bolts. Painted finish. Split top Cast Aluminum Standard Ventilated Well Cap with Conduit Opening Standard 4". 5" and 6" cast aluminum well caps for use on steel or plastic casiing. Stainless steel set screws Submersible Pump CablePackaged 12/4 (3-wire plus ground) UL approved 3 wire stranded copper cable (with ground) with thermoplastic rubber insulation for use in water wells. Includes attached motor connector. No underwater splicing required. Strataflo Noiseless Check Valves - Brass Spring LoadedStrataflo bronze spring loaded check valve. For cold water service to retain liquid in a system preventing loss of prime when liquid source is lower than pump. It prevents backflow by allowing liquid to flow in one direction only. Pressure Relief Valve 1/2" (Set 100 PSI) # RV50-100 (A)Pressure relief valve 1/2" heavy duty bronze pressure relief valve for shallow, deep well and submersible pumps. Recommended only for cold water system installation. Spring loaded and pre-set at 100 PSI (Not adjustable). Not for use with hot water heaters. WellMate Fiberglass Bladder Water Pressure TanksWellMate fiberglass bladder water pressure tanks are quicker, easier and less costly to install than steel tanks. They contain no steel, so there is no paint to scratch or touch-up and they cannot rust. All component materials are NSF and/or FDA listed. 2" Liquid Filled Pressure & Vacuum GaugesGlycerine liquid filled 2" , 1/4" MNPT bottom connection, 2% accuracy, vacuum and pressure gauges with steel case and plastic lens for high vibration applications in 30 to 160 degrees Fahrenheit temperature. Pressure Switches For Water PumpsThe pressure switch starts and stops the pump motor automatically at a predetermined pressure. A tube connects the switch to some point in the system on the discharge side of the pump. The pressure in the system then acts directly on a diaphragm in the switch, which in turn actuates the contacts in the switch.
