ABSTRACT:
A vapor recovery pump for pumping flammable vapors is disclosed. The pump includes a pump unit that defines a pump chamber into which the vapor is first drawn and then exhausted from. A motor contained in a motor housing provides the motive force for energizing the pump unit. A single-piece inboard head seals the pump chamber and the motor housing and spaces the pump chamber away from the motor. Removable flame arrestor assemblies are attached to the inlet and outlet ports into which the vapor is, respectively, drawn into and exhausted from. A gland assembly integral with the motor housing provides a seal around the conductors that extend to the motor.
