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.
