Our Story

A company built around water — and the people who depend on it.

General Pump Company was founded in 1952 in the San Gabriel Valley. What began as a local water well contractor has grown into one of California’s most trusted pump and well services companies — serving water utilities, municipalities, farms, and industrial facilities across the state.

For more than seven decades we’ve operated with one principle: do the job right, stand behind the work, and treat every water system like it belongs to someone who depends on it. That hasn’t changed.

Today, General Pump Company is a Sylmar Group Company with three full-service shops in San Dimas, Camarillo, and San Bernardino, and a field service fleet ready to deploy across California.

Why General Pump

What sets us apart from the rest.

In-House Shop Capabilities

Three fully equipped shops — San Dimas, Camarillo, and San Bernardino — with a Vertical Turret Lathe, CNC horizontal lathes, precision balancing equipment, and a full machining floor. We don’t outsource the critical work.

Long-Term Client Relationships

We hold 65+ annual maintenance contracts with water utilities and municipalities across California. Our clients don’t just call us once — they rely on us year after year because we consistently deliver.
