Most hose pumps have only one connection on the pump head top: the Verderflex Smart pumps, on the other hand, are fitted with an automatic stop function to prevent disasters
The chief advantage of hose pumps - or peristaltic pumps - is that they are completely leak-free.
The only part of the pump comes into contact with the medium is in fact the hose.
The pumping action is achieved by rollers or shoes that continually press on the hose and so shift the liquid.
This means that the pump can run dry without problems, create its own suction and has no problem at all in pumping viscose or abrasive media.
Because a hose conducts the pumping action as a complete unit, no seals are required.
This operating principle renders the hose pump fully leak-free and - provided the right hose material is used - also suitable for hygienic applications.
The operating principle has yet another merit: because an identical and constant quantity of medium is shifted at each revolution, the hose pump is ideally suited for apportioning applications.
Top loading system The new pump - the Verderflex Smart - is a low pressure hose pump with a capacity range of 0-15l/min and pressures up to 4bar (with hose diameters from 0.5mm to 25.4mm).
It differs from the average hose pump through the design of the pump head and drives.
A good example of user and maintenance thinking: the hose is placed in the top side of the pump head and the loading system differs from the traditional U-shape.
For this design, Verder looked at ski-boot fastenings that can also be clicked shut with one hand.
These self-regulating hose clips make further action unnecessary to fasten the hose.
The shape of the hose clips prevents buckling in the hose.
The right hose throughput extends the working life of the hose.
The top loader system also allows several pump heads to be linked, each of which can be exchanged separately from the hose without the other hoses being shifted from their position.
In practice, up to four pump heads can be fitted.
In other words, different pumping processes can proceed next to each other through one and the same pump.
The adjustable feet ensure a stable position for the pump.
If non-pulsing operation is needed, a second pump head can be connected up to overlap the pulses.
Most hose pumps have only one connection on the pump head top: the Verderflex Smart pumps, on the other hand, are fitted with an automatic stop function to prevent disasters.
Verder is marketing the new pump with three different drives: standard on/off, left/right functions; externally controlled version and programmable computer control.
The pump is fitted as standard with a safety stop.
With applications where full control is required over the process, an optional leak detector can be installed, stopping the pump automatically and/or providing an alarm signal.
The pump head has its own bearings, so that pressure on the drive is reduced.
This gives the pump a longer working life.
The central display lights up and can be easily read from any angle.
The menu is designed for ease of navigation and a logic process.
Because the pump head is placed next to and not beneath the display, it is simple for both left and right handed people to easily operate the pump.
The various buttons on the display are large enough to operate without problems (even when wearing safety gloves).
