The patented roller-and-tube pump head keeps the solution completely isolated from the motor and gearing, so there are no seals, valves, or check balls to wear out or clog. The pump is self-priming against full working pressure, won't lose its prime or vapor-lock on off-gassing chemicals like sodium hypochlorite, and can run dry without damage. The 170 Series is Stenner's highest-capacity double-head Classic pump, pairing two independent heads on one motor for up to 170 gallons per day of combined output or matched dual-chemical dosing. An external feed-rate dial adjusts both heads together from roughly 5% to 100% of rated capacity. It's the standard choice for well water chlorination and disinfection, pH correction, iron and manganese oxidation ahead of a filter, corrosion and scale control, and commercial pool and spa sanitation, and is also widely used in cooling towers, irrigation, animal health, and industrial process water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMaximum Output: 170 GPD\u003c\/li\u003e\n\u003cli\u003eMaximum Working Pressure: 25 PSI\u003c\/li\u003e\n\u003cli\u003eMotor Voltage: 220V, 60Hz\u003c\/li\u003e\n\u003cli\u003eSuction\/Discharge Tubing: 3\/8\" Santoprene\u003c\/li\u003e\n\u003cli\u003eTwo independent pump heads driven by one motor for dual-chemical or higher-volume dosing\u003c\/li\u003e\n\u003cli\u003eExternal feed-rate dial adjusts output on both heads together, in 2.5% increments\u003c\/li\u003e\n\u003cli\u003eSelf-priming against maximum working pressure; no foot valve required\u003c\/li\u003e\n\u003cli\u003eWon't lose prime or vapor-lock on off-gassing solutions, and can run dry\u003c\/li\u003e\n\u003cli\u003eTool-free pump tube changes; no lubrication required\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Stenner","offers":[{"title":"Default Title","offer_id":48804999332096,"sku":"170JL5B4STAA","price":700.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/2222\/3360\/files\/Double-Head-Adjustable_518f7001-751b-4596-af8b-d4621439363b.jpg?v=1780677282","url":"https:\/\/waterpumpspro.com\/products\/170jl5b4staa-stenner-170dm5-double-head-adjustable-pump-220v","provider":"Water Pumps Pro","version":"1.0","type":"link"}
