VOLTECH develops a wide variety of pump heads and adjustment options which makes VIP metering pumps truly versatile.

 


ACCESSORIES:
Avilable a safety valve, Strainer, Back Pressure Regulator, Pressure Systaining valve, Calibration pot, Pulsation Dampener.

SPECIAL FEATURES:

Accuracy - Totally enclosed, water and dust proof housing - wide capacity range - fully automatic lubrication - compact - light weight - wide range of heads - multiplexing choice of different type and capacities can be achieved by multiplexing - easy avilability of spares - before shipment, each pump is fully tested and approved to perform to exact requirements.

THE ADVANTAGES:
- Oil immersed operating assemblies for continuous operation. - Automatic gas venting of hydraulic oil.
- Variety of check valves designs for difficult liquids.
- Special 'U' spring loaded seals.
- Relief and replantig valve in hydraulic circuit.
- Relatively better resistance to fouling.
- Long working life to PTFE Diaphragm and gentle flow against the diaphragm.

PRINCIPLE:-
VIP Dosing/metering pump is precise volumetric control metering pump for feeding, measurement and control system. It is positive return type plunger.Diaphragm pump where flow can be adjusted from 0 to 100% while the pump is running or at rest by stroke changing mechanism. Reciprocating motion to achieve desired fluid control by stroke setting micrometric manual adjustment or pneumatic or elecrical actuators.

THE DESIGN:-
VIP unique design for accurate dosing the plunger stroke length must be adjustable with almost precision from ZERO to 100% of maximum of stroke length in power end mechanism most important design for accuracy is connecting ball joint with piston and eccentric disc. variations in the discharge capacity are by micro-mereic adjustment or pneumatic or electrical.
ZERO STROCK
High rotary motion is transmitted by craft make high speed worm to wheel in a perpendicular plane, the crank disc also revolves in the perpendicular plane which eliminates reciprocating action in the cross head and plunger rendering the pump to a zero stroke.
FULL OR PARTIAL STROKE
For 100% or at any internal stroke setting worm gear is adjusted away from the perpendicular plane i.e. the eccntric disc move back off the perpendicular axis. As the connecting ball joint transmits a reciprocating motion to the crosshead and plunger. In such position the pump is at 100% or at partial stroke setting as the case may be stroke length adjustment by changing the radius of the reciprocating crank eneuides near harmonic motion for the plunger travel at all stroke length the ball checks on suction and discharge are synchronized to respond resulting in to efficient operation of the pump.
VALVES:-
Metering pump check valves are heart of the pump performance, Precision and accuracy depend on the correct shape and design to suit for known Fluid characteristics.
In addition to above , VIP has special designs of value like:
1. Slurry valves
2. High Viscocity valves
3. Soft seal valves
4. Special Metal Valves
5. Inverted Design Valves.
