Abstract: 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.

Abstract: 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.

Abstract: A paint sprayer includes an end bell, a motor connected to the end bell, a pump drive connected to the end bell, a pair of protrusions attached to an extending from the end bell such that each protrusion is cantilevered from the end bell, and a pump assembly comprising a pair of mounting holes and containing a piston. The pair of mounting holes is adapted to receive and slide onto the pair of protrusions to mount the pump assembly on the end bell as well as slide off of the pair of protrusions to remove the pump assembly from the end bell. The pump drive is configured to covert rotational motion output by the motor to reciprocal motion. The pump assembly is configured to pump paint when reciprocated by the pump drive while mounted on the end bell.

Abstract: A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

Abstract: A pump rod has a head extending from a neck, and the head is received within a drive slot of a drive link. The head includes a projection, and has an area smaller than an area of the head. The projection contacts an inner surface of the drive slot. The drive link may include a projection aligned with a centerline of the drive link. The drive link projection contacts a head of the pump rod. The projections provide a reduced contact area between the pump rod and the drive link, thereby reducing any side-loading on the pump rod and increasing a lifespan of the wear parts.

Abstract: A system for generating and dispensing plural component materials includes a controller operatively connected to dispense valves and return valves. The return valves are in respective open states to allow constituent materials to circulate back to a source and are in respective closed states to block circulation. The dispense valves are in respective open states to allow mixing of the constituent materials to form the plural component material and in respective closed states to prevent generation and dispense. The controller implements a delay between closing the return valves and opening the dispense valves to build pressure in the system prior to generating and dispensing the plural component material.

Abstract: A mixing module includes two inlets, an integrator, and a valve member. The integrator has two chambers each having a near end and a far end, and the valve member is movable between two positions. One of the inlets is connected to the near end of one of the chambers and the other inlet is connected to the near end of the other chamber when the valve is in one position. When the valve is in the other position, one of the inlets is disconnected from the chambers and the near ends of the chambers are connected.
