PERISTALTIC METERING PUMPS HELP

PREVENT BOILERSCALE BUILD-UP

THE CHALLENGEThe customer was using a solenoid-activated diaphragm meteringpump to inject an anti-scaling chemical into their boiler. The companythat supplied the pump and monitored the water reported highquantities of scale build-up in the boiler regardless of the amount of anti-scaling solution they used.

The problem was that the check valves on the pump's head were clogging and causing the pump to lose its prime and ability to provide a suction lift of the chemical out of its container. This in turn, preventedthe proper amount of antiscalant from being injected into the boilerwater. Without enough of an antiscalant dose in the water, significantamounts of scale began to build up over time within the boiler. Thisscale & rust build-up decreased the boiler's efficiency, increased thecompanies operating and maintenance costs, and had the potential tobecome a dangerous situation had the scale began to plug some of theboiler tubes.

THE SOLUTIONOur application expert—Joe Marotta—talked with the customer about their pump issues and offered up peristaltic pumps as a solution. He recommended a peristaltic pump because of its seal-less design and its ability to operate without check valves in the pump head. Why this type of pump: the valves can’t clog up if there aren’t any valves! A peristaltic pump, like the Pulsafeeder Chem-Tech XP model that was recommended in this case comes with a meagre maintenance cost because it only has one tube, which a serviceperson can change out very quickly and easily. The pump also has the added benefits of dry-run capabilities and is, of course, self-priming.

HOW IT WORKSA rotating shoe passes along the length of the hose, creating a seal between

the suction and discharge side of the pump.

As the rotor turns, the sealing pressure moves along the tube and pushes the

product into the discharge line.

When the pressure releases, the hose recovers, creating a vaccum that draws

the product into the suction side.
