Product Description
PENTAIR STA-RITE HS Series 7GPM Wet Ends
Pentair Sta-Rite HS Series Stainless Steel 4" Submersible Pumps
Precision-engineered, high-quality, rugged Signature 2000® Stainless Steel Series Pumps deliver efficient, dependable performance even in rough, aggressive water. Heads to 1,950 feet and capacities to 65 GPM. Built to deliver long-term, trouble-free service. Floating impeller design resists sand and reduces sand locking. These pumps feature the proven SignaSeal™ staging system.
KEY FEATURES
SignaSeal staging system incorporates a harder-than-sand ceramic wear surface and a floating impeller design - which together literally pulverize sand and small debris. This proven feature reduces lock-ups, dry-runs, and abrasive wear.
Floating Stage Design is engineered to transmit forces away from the motor bearing and through the pump housing. This reduces premature wear and misalignment.
Fully-Enclosed Shaft Bearing creates a pressure zone that prevents sand & water from entering. Eliminates wear and misalignment.
Wear Ring forms a seal between impeller hub and suction cap for low friction and no unwanted recirculation of water.
Corrosion resistant 300 grade stainless steel discharge for durability in aggressive water.
Large octagon wrench area for ease of installation.
50 GPM series does not include motor.
