Griswold Pumps FAQ
What are Griswold pumps used for?
Griswold centrifugal pumps move liquids in chemical processing, water management, energy, mining, and general industrial applications. The selected configuration must match the fluid and operating requirements.
Which pump series does Griswold offer?
Griswold's lineup includes the 811 ANSI, 811SP, 811CC, 850, and H Series. These families provide different options for process service, compact installations, and water handling.
What is the Griswold 811 ANSI Series?
The 811 ANSI Series consists of centrifugal process pumps built around ASME B73.1 requirements, with multiple construction and configuration options.
Does Griswold offer self-priming pumps?
Yes. The 811SP and H Series include self-priming designs. Their application limits differ, so confirm the specific model's suitability for the liquid and suction conditions.
What is the Griswold 811CC Series?
The 811CC is a close-coupled design that provides a compact alternative within the 811 family. It can be considered where installation space is limited.
What applications suit the Griswold 850 Series?
The 850 Series is designed for a variety of water-pumping duties. Selection should account for the required flow, head, temperature, and installation conditions.
How does a centrifugal pump move liquid?
A rotating impeller transfers energy to the liquid, while the pump casing directs flow toward the outlet. The resulting pressure difference moves liquid through the connected piping system.
Can Griswold pumps handle process chemicals?
Suitable configurations can. Check the casing, impeller, seals, and elastomers against the chemical's composition, concentration, and temperature.
What information is needed to select a Griswold pump?
Provide flow, total dynamic head, suction conditions, liquid properties, temperature, and solids content. Include power availability and installation constraints.
Why should a replacement be selected using more than horsepower?
Equal horsepower does not mean equal hydraulic performance. Compare pump curves, materials, speed, connections, and operating limits to determine whether a replacement meets the actual duty.
Does a self-priming pump still need liquid before startup?
Self-priming pumps generally require an initial liquid fill as specified by the manufacturer. Self-priming capability does not mean the pump can safely run dry.
What can cause a Griswold pump to lose performance?
Possible causes include worn components, restricted piping, air entry, or changed system conditions. Compare current operation with the original duty.
What is cavitation, and why does it matter?
Cavitation occurs when local liquid pressure drops below its vapor pressure, allowing bubbles to form and collapse. It can cause noise, vibration, and damage to internal surfaces.
What maintenance does a Griswold pump require?
Follow the model's manual for lubrication, alignment, seals, bearings, and inspections. Track changes in vibration, temperature, flow, and pressure.
Can Industrial Air Services help repair or replace a Griswold pump?
Yes. Industrial Air Services provides troubleshooting, maintenance, repair, and replacement assistance. Equipment condition and current system requirements help determine the appropriate approach.
