Also for use with older W, D & K Series Metering Pumps INSTALLATION, OPERATION AND MAINTENANCE MANUAL HI PRESSURE - FLOW PLUNGER

This manual contains specific, comprehensive procedures to help users install, operate, and maintain the Williams Plunger Series of Pneumatic Metering Pump Assemblies consisting of a plunger pump and controller or a plunger pump, relay, and controller. For user convenience, the manual is divided into five sections: FUNCTIONAL DESCRIPTION Section 1.0 contains a physical operating sequence of the pumps. Section 2.0 contains specific proce- dures for installing the pumps and their various components including STARTUP, OPERATION, AND SHUTDOWN Section 3.0 contains procedures for setup,...

Section 1.0: Functional Description 1.1 Physical Description The letters CP at the beginning of a pump assembly model number indicate that the model consists of a controller and pump. The letters CRP indicate that the model also has a relay. Controller types differ according to the pump model. • CP250K, CP125D and CP250D225 pump assemblies use the MK-II controller. • CP250D300 and CP500D pumps use the MK-VII controller. • All W series pumps--CP125W125, CP250W225, CP500W300. etc.--use the MK-X controller. Some W series pumps use relays which are of different sizes: • CRP500W400, CRP1000W400,...

DRAWING 1 GENERAL CONFIGURATION

CAUTION To prevent damage to the controller, always use a regulator between the supply and the controller when the air/gas supply pressure is more than the maximum rating of your controller. 1.2.1.2 Relay Supply Pressure: Relays, which require a separate air supply, operate with supply pressures of 50 psig (3.4 bar) minimum and 150 psig (10.3 bar) maximum. The supply pressure must be equal to or greater than the process pressure plus 200 psig divided by the pump amplification ratio. (See 1.2.1.1 above for definitions of process pressure and amplification ratio.) When using a...

1.3.3 Pump Motor (Air Chamber) The motor forces the piston plunger to move alternately into and out of the pump chamber. When the controller sends the supply air/gas into the motor chamber through the nipple connector, the pressure on the U-cup and piston plunger overcomes the combined force of the process fluid pressure on the U-cup and piston plunger overcomes the combined force of the process fluid pressure on the U-cup, piston plunger, and plunger return spring and pushes the plunger into the fluid chamber. When the external controller exhausts the air/gas, the piston plunger return...

If the controller stroke rate has not been calibrated already, follow this procedure: 1. Rotate the stroke rate knob on the controller clockwise (CW) to ZERO on the stroke rate scale. 2. Turn the main air/gas supply to the regulator(s) to ON, and adjust. (See 3.1.1.1 above.) 3. Set the desired flow rate for your application by using the pump's stroke adjuster in combination with the controller's stroke rate adjustment. ( Ref. 1.2.2.5 FOR PUMP PERFORMANCE) 1. Set the stroke rate knob to a point on the scale that will product a stroke rate close to the one you want. 3. You may leave the pump,...
