A clamp for sanitary pumps includes a tensioning assembly mounted on a ring. The tensioning assembly includes an adjustment assembly that interfaces with first and second brackets disposed at first and second ends of the ring. The adjustment assembly includes a nut that interfaces with a rod at a threaded interface. A head is disposed at an end of the rod opposite the nut and interfaces with the second bracket. The nut and rod are coaxial and an orientation of a common adjustment axis can be changed by pivoting the adjustment assembly relative to the first bracket, to maintain concentricity between the nut and rod.

Sanitary clamp for diaphragm pump covers

A displacement pump includes an electrically powered drive having a drive housing. The drive is at least partially disposed in the drive housing and is configured to provide reciprocating linear motion to a diaphragm. The diaphragm is captured between an adaptor mountable to the drive housing and a fluid cover. The adaptor includes an inner mounting portion interfacing with the drive housing and an outer mounting portion interfacing with the diaphragm. Multiple adaptors having multiple outer mounting portion diameters can be mounted to the same drive housing. Each of the multiple adaptors have the same inner mounting portion configuration to mount to the same drive housing. The adaptors can mount to the drive housing in multiple orientations while the fluid cover can mount to the adaptor in a single orientation.

Diaphragm pump drive for an electric pump

A drive system for a pump includes a housing and a fluid displacer and a reciprocator configured to mechanically displace the fluid displacer through respective suction strokes. The housing and fluid displacer define an internal pressure chamber configured to be filled with a working fluid having a charge pressure. The internal pressure chamber is configured such that the working fluid exerts the charge pressure on the fluid displacer during both the suction stroke and a pressure stroke of the fluid displacer.

Drive system for a positive displacement pump

A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston disposed within a cylinder. The piston is configured to pressurize at least one pumping chamber. A motor is coupled to the housing and connected to the reciprocating piston fluid pump to actuate the piston. A wobble assembly connects the motor to the piston of the reciprocating piston fluid pump. A spray tip connected to an outlet of the at least one pumping chamber.

Portable airless sprayer

An electrically operated displacement pump includes an electric motor having a stator and a rotor. The rotor is connected to the fluid displacement member to drive axial reciprocation of the fluid displacement member. A drive mechanism is disposed between and connected to each of the rotor and the fluid displacement member. The drive mechanism receives a rotational output from the rotor and provides a linear input to the fluid displacement member. A controller controls operation of the motor based on an operating state of the motor to control pumping by the displacement pump.

Electrically operated displacement pump control system and method

Modular mechanically driven diaphragm pump features are presented herein. Such a diaphragm pump can include a motor, a drive mechanism, and a coupling mounted on a wheeled frame. A diaphragm pump can be mounted to the coupling by forming mechanical static and dynamic connections to brace a housing of the diaphragm pump relative to a drive rod which is moved by the drive mechanism to operate the pump. These mechanical static and dynamic connections can be broken to dismount the pump for replacement or servicing. In some cases, a gas charge can be introduced on the non-working fluid side of the diaphragm to boost performance and/or a dampener can be integrated into the housing of the diaphragm pump and mounted/dismounted with the diaphragm pump.

Displacement pump

Displacement pump control box with center section

A displacement pump has multiple gas compression stages and serial gas flow through the compression stages. The gas is initially compressed in a first compression stage by a first fluid displacement member. The gas from the first compression stage flows to a second compression stage. The gas in the second compression stage is compressed by a second fluid displacement member and output from the pump.

Pump having multi-stage gas compression

A drive system for a pump includes a housing, first and second fluid displacement members, and a reciprocating member configured to mechanically displace the first and second fluid displacement members through respective suction strokes. The housing and fluid displacement members define an internal pressure chamber configured to be filled with a working fluid having a charge pressure. The internal pressure chamber is configured such that the working fluid simultaneously exerts the charge pressure on the first and second fluid displacement members.

A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston. The piston is configured to pressurize at least one pumping chamber. A motor is connected to the reciprocating piston fluid pump to actuate the piston. A spray tip connected to an outlet of the at least one pumping chamber.
