For over 60 years Claypool Pump & Machinery has maintained its reputation as the best St Louis pump company

St Louis Pump Company

Claypool Pump & Machinery was founded in 1946 by Ralph Claypool and has operated under family ownership in the St Louis area for the last 68 years. In that time Claypool Pump & Machinery (CPM) has been a trusted supplier of pumps and associated equipment for the commercial, industrial, municipal, and fire protection markets.

Claypool Pump & Machinery offer you pre-sales project design, a complete offering of equipment for all of your application needs, and a full service repair shop for any maintenance or St Louis pump repair you may require.  Whatever your application: hot/chilled water systems, HVAC and cooling towers, fire pumps, industrial or process, and waste-water, we have a cost effective, timely, and informed solution. Our knowledgeable staff has over 100 years of combined experience in the commercial, fire, municipal, and industrial markets. Claypool Pump & Machinery’s large selection of products from the world’s best manufacturers, make us a leading St Louis pump distributor in custom pump sales in the Eastern Missouri and West Central Illinois areas.

With a working knowledge of almost every pump type and accessory for any pumping application, you can depend on our expertise and guidance to find solutions for your unique problems. If you need assistance to troubleshoot or to replacing a current installation our staff is ready to lend a hand.  We wouldn’t be the best St Louis pump company without offering custom services either.  For applications that require more complex pumping solutions (for example water solids pumping or fire department pumping projects), please don’t hesitate to contact us and we can work with you to identify the requirements, design a solution and select the right mix of pumping products that will help to deliver quality, long lasting performance.
