Pneumatic Chemical Metering Pump

Transcription

1 Timberline s was designed with the well pumper and the chemical man in mind. Each pump has a simple but rugged design that can be repaired in the field within minutes on the tailgate of a pickup truck. Standard features include wetted parts, TFE o-rings in both checks, sealed lube system, and a timer/controller that will turn down to 3 strokes per minute. For chemical injection applications where a pneumatic pump is the right choice, the Timberline is the ideal pump to meet your needs. Springs are engineered for optimum performance and for long life. Exhaust gas from both the piston housing and the controller can be vented to a safe area. The bleed screw is designed to accept a hose to allow collection of chemical. Features: Materials of Construction: Dual seals and a piston wear guide (2.25" pistons and larger) ensure concentric plunger stroke and longer seal life. The pump will continue to function properly even after the lower seal has failed. By adding a gauge to the lubrication system the lease operator can determine if maintenance on the pump is required. If maintenance is necessary the operator can order parts and schedule the maintenance at his convenience. Sealed lubrication system Lubrication changed only when seals are replaced.

10 Installation The pump must be installed in the vertical position with the suction check valve pointing straight down. Typical installations will include the following: A rate gauge or drum gauge to accurately set the injection rate The chemical supply level should be at least 6 above the suction check valve at startup Separate regulators when a relay is used in conjunction with the timer To prevent restricted supply gas, always mount the supply regulators as close to the pump as possible (no more than 6 away when using /4 tubing) Isolation valves on the suction, discharge, and supply lines Line check on the chemical discharge line Caution: If the discharge piping is not rated equal to or higher than the maximum discharge pressure rating of the pump then a relief valve should be used. Startup. Loosen bleed screw until the chemical is coming out of the end. Tighten as the pump is making a down stroke. 2. Set supply pressure so that the discharge pressure is 200psi above process pressure. 3. Set the injection rate by timing the suction rate from the rate gauge for one minute. Adjust the rate by rotating the set-point knob on the timer. 4. Adjusting the stroke length of the pump will also change the injection rate. 5. If no rate gauge is available you can set the rate by counting the number of strokes per minute. Then multiply the total strokes by the amount of fluid injected per stroke (see table). Maintenance Add or replace lubricate as required (usually when repairing pump). Use lubricant suitable for climate where the pump is installed. Troubleshooting Problem Possible Cause Corrective Action No supply gas/air. Check supply side gauge. Setting should be Timer not cycling 20 to 50 psi. Supply through to exhaust port Pump not stroking Low or no pump output Stroke rate adjustment knob closed. Stroke rate adjustment knob, open too much. Trash in seat. Bad soft goods in timer. Broken return spring. No output from timer. Supply pressure to low. Plunger stuck due to low lubrication. Discharge or suction line plugged. Pump mounted too high to create adequate suction. Viscosity of injection chemical too high. Air/Vapor in pump. Turn adjustment knob counter clockwise to proper setting. Turn adjustment knob counter clockwise to the proper setting. Disassemble timer and remove any foreign material. Install timer repair kit (TRK). Replace spring. Trouble shoot timer. Increase supply pressure to timer. Add lubricant. Clean lines. Mount pump a minimum of 6 below chemical. Increase suction & discharge line size. Bleed pump per startup procedure. Page 0
