Top discharge 316 cast stainless steel pumps. Top discharge pumps pass the liquid up and around the motor before discharging. This ensures better motor cooling in low level liquid applications. RX pumps are available in one (1) and two (2) HP, in single phase and three-phase. Class F insulation and overload protection ensures a long life. RX models are delivered standard with 2” stainless NPT discharge connection.(3" adapter available).
All wear and "wet" parts such as impeller, wear-plate, oil housing, pump-housing and inner pump top are made of Cast 316 stainless material. The elastomers such as o-rings, lip seals and gaskets are made of FKM. Standard power cable is made of oil-resistant material. Special installation can be made with EPDM power-cable and elastomers. (BUNA (Nitril) also available).
Three Seal Motor Protection - Motor is protected by double mechanical seals. Lower seal made of silicon carbide/silicon carbide and upper seal is made of carbon/ceramic. An additional lip seal has been installed above the impeller, to help prevent abrasives such as dirt, silt or sand, from entering into the seal chamber. More Motor Protection – Winding protection and (NEMA) Class F motor insulation allows motor temperature to raise to 230°F, superior to pumps with Class A and B insulation. Automatic switch turns pump motor off if temperature and/or amp draw raises too high. When the motor cools the switch will automatically reset and the pump will turn back on. Each pump is tested at factory, both for performance as well as safety. Level controls and level control systems are available.
