"V" Pump Features
Stroke Adjuster is made more compact and adjustment is simplified with an internally threaded design. The positive locking device to hold stroke length is readily accessible and easy to operate.
The Pneumatic Piston and Fluid Plunger Assembly is guided at both ends on TFE composite bearings ensuring concentric movement of the plunger though the seals.
The clearance between the return spring and plunger has been optimized to eliminate any possible contact.
A true double sealing arrangement is used so that secondary seal containment is provided.
Lubrication has been simplified with the use of synthetic grease. The lubrication chamber is filled once over the life of the seals.
The bleeder is equipped with a barbed fitting for plastic tubing so that the fluid bled from the fluid chamber can be collected.
Both the discharge and suction check valves have tough TFE composite seats for long life and positive sealing.
Threaded port after the secondary seal provides for the indication, collection or containment of any seal leakage
POWER STROKE: As the CONTROLLER air or gas enters the PNEUMATIC DRIVE CYLINDER, the PISTON-PLUNGER ASSEMBLY is driven down into the FLUID CHAMBER, displacing fluid and compressing the RETURN SPRING. As the plunger displaces the fluid, the rise in pressure closes the SUCTION CHECK VALVE and opens the DISCHARGE CHECK VALVE. A precise amount of fluid, corresponding to the stroke of the plunger, is discharged.
SUCTION STROKE: When the air or gas is exhausted from the PNEUMATIC DRIVE CYLINDER the RETURN SPRING forces the PISTON-PLUNGER ASSEMBLY to return to its original position. The drop in pressure in the FLUID CHAMBER caused by the retraction of the piston allows the spring loaded DISCHARGE CHECK VALVE to close and the SUCTION CHECK VALVE to open so that the FLUID CHAMBER is again filled and ready for the power stroke.
