A metering pump includes a motor having a motor shaft extending through a drive housing, a carriage assembly disposed around the motor shaft and within the drive housing, a plunger return block mounted to the carriage assembly, a piston disposed along an axis, a carriage bearing disposed on the motor shaft and within the carriage assembly and slidably coupled to the carriage assembly, a cam coupled to the motor shaft to rotate with the motor shaft, and a bearing disposed around the cam to rotate therewith and to contact the stroke adjuster and the plunger return block. The piston also includes a stroke adjuster mounted to the carriage assembly, a plunger having a button-shaped protrusion end, and a drive shaft having a first end connected to the stroke adjuster and a second end having a hook protrusion configured to receive and engage the plunger button-shaped protrusion end.

A pneumatic timing valve includes a spool and seal system having a first seal cartridge and a spool. The first seal cartridge has an annular body with radial ports. The spool is positioned within the first seal cartridge and movable between a first and second position. The spool has a central bore and radial ports that intersect the central bore. The radial ports of the spool complement the radial ports of the seal cartridge. The seal cartridge radial ports, the spool radial ports, and the central bore of the spool define fluid flow passages.

A metering pump includes a motor having a motor shaft extending through a drive housing, a carriage assembly disposed around the motor shaft and within the drive housing, a plunger return block mounted to the carriage assembly, a piston disposed along an axis, and a carriage bearing disposed on the motor shaft and within the carriage assembly, slidably coupled to the carriage assembly, and configured to provide a second contact point for maintaining the alignment of the carriage assembly with the axis of the piston. The piston further includes a stroke adjuster mounted to the carriage assembly to provide a first contact point for maintaining the alignment of the carriage assembly with the piston, a drive shaft connected to the stroke adjuster, and a plunger connected to the drive shaft. The metering pump also includes a cam coupled to the motor shaft to rotate with the motor shaft and a bearing disposed around the cam to rotate therewith and to contact the stroke adjuster and the plunger return block.

Pump transmission carriage assembly

A modular platen assembly comprises an annular hub, a wiper ring assembly and a coupling ring. The annular hub is for connecting to a ram of an inductor pump. The wiper ring assembly includes an annular wiper for sealing with a container. The coupling ring is independently joined to the hub and the wiper ring assembly at first and second connections, respectively.

The outer case of the display moduleis constructed of static dissipative polypropylene components that house a circuit boardand displayWhen the display moduleutilizes the hand held pendant option a front coveris used. This front coverprovides a viewing windowto the displayand a flat surface to attach the membraneWhen the display moduleis to be mounted inside of an enclosure, the front cover is replaced by a flat platethat then provides the viewing windowand flat surface membranerequirements. The rear portionof the display moduleis used with either option and contains the necessary features to allow for either the front coveror the flat plateto be attached.
