Finland food processor Pakkasmarja Oy has selected the Verderflex VF32 peristaltic hose pump to replace a rotary lobe pump on its fruit sorbet and puree production line.

All of the company’s products are made from fresh ingredients but the seeds in the fruit pulp constantly wore the previous pump’s lobes, ultimately causing its failure.

Its replacement by a peristaltic hose pump restored productivity and provided greater production flexibility.

The Verderflex VF32 peristaltic hose pump was ideal for this application for a number of reasons.

It can pump liquids including hard or abrasive solids in suspension by passing a rotating shoe along a specially designed hose, compressing it completely until, on recovery, a strong vacuum is produced giving the pump a powerful self-priming capability.

The pumped product is completely contained within the hose without coming into contact with any other part of the pump.

As the pump has no valves to clog or moving parts to wear out, the Verderflex VF32 provides Pakkasmarja Oy with a pump that can transfer viscous liquids without compromising production line efficiency or plant reliability.

A combination of a food-grade NBR hose and hygienic SMS flanges provided a hygienic pumping solution.

This Verderflex VF32 has its speed controlled by a variable frequency drive, adding greater control to the production process, varying the delivered flow between 20 and 2,000 l/hr.

Verderflex was also able to meet the customer’s request for the pump to be dual-use by mounting the pump on a trolley, so Pakkasmarja Oy can move it from the production line to the packaging area to feed a loading hopper when it is not being used for pumping fruit pulp.

The first Verderflex VF32 has been such a success that Pakkasmarja Oy has ordered a second VF32 pump.
