Is the PR4 suitable for both dishwashers and glasswashers?

Yes, the PR4 is designed for use with commercial warewashing equipment generally, including under-counter dishwashers and glasswashers. The adjustable dosing rate means it can be set to suit different machine types and detergent concentrations, though it is worth confirming compatibility with your specific machine manufacturer if you are in any doubt.

Does the PR4 need to be installed by a qualified engineer?

Installation is straightforward, but correct positioning relative to the detergent container and machine draw point is important for reliable priming and consistent dosing. We would recommend having the pump fitted and commissioned by a qualified engineer or service technician to ensure it is set up correctly from the outset.

What should I check if I am switching to a different detergent product?

If you change detergent, it is advisable to check the viscosity and concentration of the new product with your chemical supplier before adjusting the pump setting. Significant differences in viscosity can affect flow rate and priming, so the dosing rate may need to be recalibrated to maintain consistent wash performance.

Product Description

The Seko PR4 is a peristaltic dosing pump designed to deliver liquid detergent to commercial dishwashers and glasswashers at a controlled, consistent rate. Peristaltic pumps work by compressing a flexible internal tube to move fluid, which keeps the chemical entirely isolated from the pump mechanism. This reduces wear on internal components and makes the unit practical to service without specialist tools.

In a commercial warewashing setup, accurate chemical dosing has a direct bearing on wash quality and running costs. Underdosing results in poor wash performance; overdosing wastes chemical and can interfere with rinse quality. The PR4 addresses this with an analogue speed adjustment that allows the dosing rate to be set precisely for the machine and detergent in use. Once the correct rate is established, tamper protection plugs can be fitted to hold the setting — a sensible precaution in busy kitchens where accidental adjustment is a genuine operational risk.

Adjustable output suits different detergent concentrations and machine demands
Chemical isolation from the pump mechanism reduces maintenance requirements
Compatible with wall mounting or internal fitting within most warewashing equipment
Simple trimmer adjustment keeps commissioning time to a minimum
Tamper protection maintains consistent dosing once the rate is confirmed

Installation is straightforward for a qualified engineer. Correct positioning relative to the detergent container and the machine draw point is important for reliable priming, so it is worth planning the installation carefully before fitting. If you are switching detergent products or moving from a different dosing system, confirming viscosity and concentration compatibility with your chemical supplier beforehand will save time.

The PR4 is well suited to single-site operations running one or two warewashers where a reliable, adjustable dosing solution is needed without the complexity of a larger system. Sites running multiple machines or processing higher chemical volumes may be better served by a higher-capacity dosing arrangement.

If you are not certain whether the PR4 is the right match for your machine or detergent, our team is happy to talk it through before you place an order.
