Abstract

A pump assembly includes a pump and a base. The pump has mounts located at multiple positions on the pump to effect different configurations of the assembly. Each mount includes two engagements spaced apart on the pump. The base has a retainer constructed to slidably engage one engagement and a seat constructed to support the other engagement. The seat has a socket with two holes extending into the base. A bracket includes a jaw engageable with the second engagement and two locking pins extending from the bracket for sliding engagement with the socket. The locking pins retain the bracket and jaw from moving away from the base. A fastener engages the bracket with the base so the two locking pins cannot slidably disengage the socket.

Abstract

A magnetically engaged pump includes a pump housing (10) with a rotatable magnetic drive assembly (28), a cylindrical canister (52) and a rotatable driven magnet assembly (34). This magnetic coupling is associated with a pump rotor (58) and a laterally positioned gear wheel (64) to define a gear pump. This magnetic coupling is alternatively associated with a pump rotor (58) with an impeller (118) to define a centrifugal pump. Either pump includes a stationary shaft (40) to mount the driven magnet assembly (34) and pump rotor (58). A rotatable carrier (68) with bushings (80, 82) and thrust bushings (88. 90) coaxially supports the rotatable driven magnet assembly (34) and pump rotor (58).

Abstract

An air motor has a source of pressurized air, two air chambers, a pilot valve and a directional control valve. The spool of the directional control valve is of the unbalanced type and includes a piston surface in continuous communication with atmosphere through an exhaust port and a pressurized restricted port in alternating communication with the large end of the spool and the piston surface. The alternating communication of the source of pressurized air through the restricted port is restricted relative to the continuous communication of the piston surface with atmosphere. At the point of shift of the directional control valve, the piston surface is in communication with the source of pressurized air through the restricted port.

Abstract

An elongate air operated pump includes a pump chamber, a bladder inside the pump chamber, inlet and outlet valves to and from the chamber and an air control system. The air control system includes a control valve alternately communicating compressed air and exhaust to atmosphere to a venturi with a first end, a second end and a throat port. The first end of the venturi receives continuous compressed air. The second end receives the alternately communication of compressed air and exhaust to atmosphere from the control valve. The throat port of the venturi is in continuous communication with the bladder to pressurize and draw a vacuum on the bladder. The valves may be pneumatic pinch valves controlled by the control valve to cycle with the bladder or passive one-way pump valves.
