  • Patent number: 10704539
    Abstract: 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.

  • Patent number: 10688509
    Abstract: A control method for a two-component spray system having first and second pumps for separate fluid components includes registering a target spray pressure, registering a material-specific pressure factor margin, sensing an output pressure of the second pump, and identifying a failure condition in the event that the sensed output pressure remains further than the pressure factor margin from the target spray pressure for at least a threshold time.

  • Publication number: 20190270101
    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.

  • Publication number: 20190118201
    Abstract: A method of actuating a double-action pump assembly with a reciprocating plunger includes signaling the reciprocating plunger to stop for a changeover period; while the pump is stopping, signaling the first inlet and outlet valves to close; while the first inlet and outlet valves are closing, signaling the second inlet and outlet valves to open, such that the second inlet and outlet valves begin to mechanically open at least a dwell period after the first inlet and outlet valves have entirely closed; and signaling the reciprocating plunger to begin moving while the second inlet and outlet valves are closing.

  • Publication number: 20160319812
    Abstract: 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.
