Griswold Pumps FAQ

What makes Griswold pumps a good choice for industrial applications?

Griswold pumps are engineered for demanding industrial environments where dependable performance, easy maintenance, and long service life are critical. They are commonly used anywhere reliable liquid transfer is essential.

What industries use Griswold pumps?

Griswold pumps are found in chemical processing plants, manufacturing facilities, food and beverage operations, pulp and paper mills, mining, water treatment plants, and many other industrial process applications.

What types of pumps does Griswold manufacture?

Griswold offers several centrifugal pump designs, including ANSI process pumps, end suction pumps, self-priming pumps, and specialty pumps built to handle a wide range of industrial fluids.

Does Process & Power repair Griswold pumps?

Yes. Process & Power provides Griswold pump repairs, preventative maintenance, troubleshooting, rebuilds, and field service throughout Memphis, Jackson, TN, Little Rock, Springdale, AR, Tupelo, MS, and the surrounding Mid-South.

Why is my Griswold pump making a grinding or rattling noise?

Grinding, rattling, or knocking sounds often indicate worn bearings, cavitation, impeller damage, loose components, or alignment issues. Identifying the cause early can help prevent more extensive repairs.

What causes a pump seal to fail?

Mechanical seals can wear over time because of dry running, excessive pressure, contamination, poor alignment, vibration, or normal operating wear. Replacing a failing seal quickly helps prevent leaks and additional damage.

Can a worn impeller affect pump performance?

Absolutely. As an impeller wears, the pump may lose flow, pressure, and efficiency while consuming more energy. Replacing worn hydraulic components can restore original performance.

How often should Griswold pumps be inspected?

Inspection frequency depends on operating hours and application, but regular checks of seals, bearings, vibration, lubrication, alignment, and operating performance can greatly reduce unexpected downtime.

Can Process & Power diagnose complete pump system problems?

Yes. Our technicians evaluate the entire pumping system—including pumps, motors, piping, valves, and controls—to determine the true source of performance issues instead of simply replacing parts.

Is rebuilding a Griswold pump worth it?

In many cases, rebuilding is a cost-effective option. Replacing bearings, seals, wear rings, impellers, and other worn components can restore performance while extending the pump's service life.

Why is my industrial pump using more electricity than before?

Higher energy usage often points to internal wear, clogged piping, poor system design, cavitation, or operating outside the pump's best efficiency point. An inspection can identify opportunities to improve efficiency.

Does Process & Power provide pump repair near me?

Yes. Process & Power supports industrial facilities throughout Tennessee, Arkansas, Mississippi, and the Mid-South with responsive pump repair, preventative maintenance, emergency service, and equipment support for customers searching for industrial pump repair near me.

Can preventative maintenance reduce emergency pump failures?

Yes. Scheduled inspections and routine replacement of wear components help catch small problems before they become major failures, reducing costly production interruptions.

How do I know if it's time to replace my pump instead of repairing it?

If repairs become frequent, replacement parts are difficult to source, or the pump no longer meets your production needs, upgrading may provide better reliability and lower operating costs. Process & Power can help evaluate both options.

Why choose Process & Power for Griswold pump support?

Process & Power delivers experienced technicians, responsive service, preventative maintenance programs, and industrial pumping expertise to help customers maximize equipment reliability and keep operations running efficiently throughout the Mid-South.
