APPARATUS, SYSTEMS AND METHODS FOR PROTECTING PUMPS

摘要

Modules for protecting pumps are provided having a sensor detecting leaks of the pump seal, a sensor detecting rain and/or a sensor detecting that the pump is running dry and thus is overheated. Each sensor communicates with a circuitry configured to shut down the pump until the problem is resolved and to send a notice or alarm to a person or a system. A reset button may be provided to override the shutdown of the pump by the circuitry. Methods of using the modules are also provided.

1. A module for protecting an electrical pump configured to pump a liquid and having a motor, a motor shaft and a seal for preventing the liquid from reaching inside a shaft housing, the module comprising a circuitry, a collector positioned below the motor shaft and on a side of the seal facing the shaft housing and a water detection sensor placed in the collector, the water detection sensor being adapted to send a signal to the circuitry to shut down the motor and generate a notice, when a portion of the liquid enters the collector due to a leak of the seal.
