Abstract: A pump features a liquid sensing device (LSD) in combination with a housing. The LSD senses the level of a liquid collecting outside the pump and turns the pump on/off for pumping the liquid. The housing includes a housing wall to contain the LSD. The housing wall has an outside wall surface with an outside sensing surface. The housing includes an inside mounting structure to mount the LSD inside the housing in relation to the outside sensing surface. The outside sensing surface has ribs extending or projecting outwardly away from the outside wall surface in order to prevent an object from being stuck on the outside sensing surface, and allow the LSD to sense the level of the liquid collecting outside the pump and touching the outside sensing surface, reducing a malfunction of the pump due to the object contacting the outside sensing surface.

Abstract: The present invention provides a pump cartridge, which is directly connected in-line with one or more filter cartridges in a mounting bracket. It may be paired with an accumulator tank for a pump version, and with no accumulator tank for a smart pump version. The inline design reduces the size of the system, the amount of connections, and the amount of hose required to install the system, which in turn reduces the space required for installation, the number of potential leak paths, and the likelihood of failure of the system due to issues with the hose.

Abstract: A pump features: A motor having a front end bell (FEB) with a coupling portion having twist lock style (TLS) connections with locking portions, and an outer surface with a detent; and a pump head (PH) including a PH portion having a PH coupling portion with corresponding TLS connections and corresponding locking portions with locking stops. The PH portion has an outer surface having a threaded orifice. The TLS connections couple together when the FEB and PH coupling portions are pushed together. The locking portions engage when the FEB and PH coupling portions twist together about the longitudinal axis of the pump. The locking stops abut against the locking portions to stop the FEB and PH coupling portions from twisting further, so the detent and the threaded orifice align to receive the LP, locking the motor and PH together.

Abstract: A pump has a signal processor, including one forming part of a printed circuit board assembly, that receives signaling containing information about a voltage supplied to a motor to run a particular pump model, and also containing information about whether a current draw of the pump is lower than a predetermined low current level or is higher than a predetermined high current level; and determines whether to shut off the pump after a predetermined time, based on the signaling received. The signal processor provides control signalling to shut off the pump after the predetermined time if the current draw of the pump is lower than the predetermined low current level or is higher than the predetermined high current level, where the predetermined low current level and the predetermined high current level depend on the voltage being supplied to the motor to run the particular pump model.
