The best in features & benefits, top Discharge - Allows for superior cooling of motor and provides a slim line design. Longer Power Cord - Standard 33ft. power cord on pumps 1/2 HP and below and 50ft. on pumps 1 HP and above. 304SS Motor Housing - Superior abrasion resistance will not wear out like aluminum motor housings when pumping sandy water.
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 (Exception: R400D impeller made of fiberglass reinforced Noryl. Lower seal 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 ºF, 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. Tough Pump Construction - Hardened cast iron stands up to rough handling and pumping sandy water unlike pumps with soft resin impellers or plastic exterior components. (Exception: R400D impeller made of fiberglass reinforced Noryl. Lower seal carbon/ceramic.)
R400D Special Feature - The Mop-Up™, pump will pump down to 1/12th of an inch. It features a special diaphragm valve that prevents water backflow.
BJM submersible pumps are field-proven to perform and deliver a long, low-maintenance service life in harsh environments. Mopping up after flooding is made easy with the model R400D. The Mop-up features a unique non-return valve built in below the impeller. The rubber clad bottom helps protect against damage to floor surfaces. Pumping down to 1/12 of an inch and starts up in only a small puddle of liquid, and features a special diaphragm valve that prevents water backflow. Perfect for easy clean up of floods, and spills in basements, businesses, industrial and recreation areas.
