Industrial Pumps & Hydronics

Specification: Chilled Water & Condenser Loops

Centrifugal condenser and chilled water pump overhaul, mechanical seal replacements, and impeller balancing.

Engineering Scope & Overview

Pumps keep the thermal lifeblood of central plants circulating. Unbalanced impellers or worn seals lead to disastrous motor burnouts and catastrophic flooding. We service base-mounted and inline pumps from Bell & Gossett, Armstrong, Taco, and Paco.

WMI Field Protocol & Certified Best Practices

• Silicon carbide and tungsten mechanical seal replacements
• Precision dynamic balancing of pump impellers to eliminate cavitation wear
• Baseplate regrouting and laser alignment to eliminate pipe strain
• Triple-duty valve and suction diffuser servicing

Frequently Asked Questions

What are the telltale symptoms of pump cavitation in a central plant?

Cavitation sounds like gravel or marbles rattling inside the pump volute. It occurs when suction head is insufficient, creating vapor bubbles that implode violently and pit the bronze or stainless impeller.

How does pipe strain ruin pump bearings and mechanical seals?

When heavy piping headers are not properly supported, their deadweight pulls on the pump suction and discharge flanges, cocking the shaft and destroying seals in as little as 48 hours.

Do you carry mechanical seal replacements for emergency turnaround?

Yes. We stock and rapidly source Viton, silicon carbide, and tungsten carbide mechanical seals for standard B&G and Armstrong pump models throughout Southern California.
