摘要： The present invention is directed to a pump and motor assembly assembled in a waterproof enclosure with external threaded connections for pump suction and discharge. The motor can be directly connected to a flexible coupling to a bi-rotational internal gear pump, having self-adjusting mechanical seals and cast iron housing. The pump and motor assembly can be mounted on a sliding base for easy access. Flex hoses can be used to connect pump suction and discharge to couplings attached to the pump enclosure. A discriminating leak detector can be installed at the low point of the pump enclosure to detect and annunciate the presence of oil and/or water.
