    Series 6200 Pneumatic Chemical Injection Pump Operating Manual Congratulations! You have chosen the finest, most versatile chemical injection pump made; designed to exacting specifications for long life, reliable performance, and low maintenance. To ensure proper operation and to maximize the Series 6200’s durability, please read and follow this manual. Failure to correctly install and maintain the pump is the primary cause of premature pump failure and voids the product warranty.

CheckPoint is available to answer your process questions or to help design and build a package system utilizing components appropriate for your application. NOTE: In Figure 1, the secondary chemical filter, vent line, and pressure regulator are optional under certain conditions but are highly recommended.

    Series 6200 Pneumatic Chemical Injection Pump Operating Manual 1.1.7 The pump may be mounted to a skid or other surface in a number of ways, however, clamping around the outside of the pump can permanently affect the cylindricity of the air motor, voiding the product warranty. This method also reduces accessibility during maintenance and troubleshooting and is therefore not recommended.
  • Page 6 Series 6200 Pneumatic Chemical Injection Pump Operating Manual NOTE: CheckPoint recommends using filtration to ensure a maximum particulate size of 140 microns. Multiple stages of filtration should be considered, depending upon the initial cleanliness level of the fluid media being pumped, to prevent cavitation and an increase in maintenance. NOTE: If premature scoring of the pump plunger or early packing failure is observed during operation, a likely cause is abrasive particles carried into the pump through the suction plumbing.

    Series 6200 Pneumatic Chemical Injection Pump Operating Manual 1.3 Connecting The Supply Gas 1.3.1 Gas supply to the pump should be clean compressed air or natural gas at 50 PSIG minimum, 150 PSIG maximum. “Clean” means free of abrasive dust, sand or other grit that could abrade the seals inside the pump. If using natural gas, it must be free of most production enhancement chemicals and certain distillate products, especially salts and certain aromatics that can attack the motor end seals and/or the metallic elements in the air motor.

GAS RECOVERY SYSTEMS - INSTALLATION 2.1.1 The exhaust gas can be exhausted directly to atmosphere, or can be recovered to a lower pressure gas system. If vented directly to atmosphere, CheckPoint supplies the pump with a muffler to reduce exhaust noise. 2.1.2 If recovering the exhaust gas, connect the gas recovery line from the process to the open 3/8”...

    Series 6200 Pneumatic Chemical Injection Pump Operating Manual 3.1.1.6 The level in the gauge should begin to fall. (If it does not, or if the level seems to go down and then back up with each stroke, refer to troubleshooting in Section 5.1 on page 11). When the liquid level in the gauge gets near the bottom of the gauge, or when one minute has expired (whichever comes first), stop timing, note the ending level on the gauge, and reopen the Chemical Supply Valve.
