The PV-Series power base gives the operator complete control over the speed at which a product is dispensed (which is not possible with the single speed power bases), the amount to be dispensed, the ability to adjust reversing of the pump after each cycle, automatic cycling and continuous dispensing. The ability to control all of these functions broadens the range of product applications.
This is essential in order to deliver a product onto a conveyor by precisely matching the speed of the belt. It also enables a product to be dispensed through a spout or a hand-held hose assembly at a speed comfortable to the operator. Control of dispensing speed is necessary when metering a product into a container where splashing must be controlled. Speed control is also essential in preventing delicate pastry shells from bursting during injection. These are only a few examples that illustrate the importance of this capability.
Each time the trigger is activated in a normal cycling mode, the unit will dispense a preset amount of product, reverse and then stop.
The reversing motion of the pump after each cycle is necessary to ensure precise product cutoff. This motion prevents dripping in higher viscosity products. However, in applications involving products with lower viscosity, dripless-valves are offered to aid in cleaner product cut off.
Automatic cycling is a function that relieves the operator from repeatedly pressing the trigger in order to cycle the unit. The amount dispensed and waiting time are fully adjustable, as they are in all of our power bases.
The continuous dispensing mode is used to pump a product for an indefinite period of time. Combined with speed control, it provides extreme flexibility in a virtually endless variety of applications.
All of the above functions are fully adjustable from the control pad and provide the user with uniformity, control and flexibility in any metering application.
