Kerr Pump and Supply, established in 1905 and located in suburban Detroit, is the most respected name in vertical process pumps. Our innovative, heavy duty, time proven design combines advanced hydraulic engineering with mechanical craftsmanship to meet a wide range of industrial applications. Each pump is engineered with the objective of performing on a continuous duty operation with the longest life and a minimum amount of maintenance. With domestically poured castings, in-house machining and assembly, we proudly place a “Made in America” label on all our Haynes Pumps.

Our Haynes pumps handle the varied requirements of metal finishing, parts washing, and industrial chemical process industries. Simplicity of design eliminates pump priming, troublesome shaft sealing problems and the inherent maintenance costs of mechanical seals.

Outstanding quality features included in every pump contributes to longer pump life. Each component has a machined registered fit at all assembly points to assure positive alignment and vibration free service. Haynes pumps are a sound investment in the best available technology – at no additional cost.

External Impeller Adjustment – Impeller can be adjusted to change running clearance, making it easy to restore near original pump performance without dismantling the pump.

Impeller – Semi-open with extra heavy vanes for outstanding performance and resistance to wear. Allows some small solids handling capability. Wiper vanes on backside of shroud prevent material accumulation and pump binding.

Throttle Bushing & Slinger – Restricts liquid from entering the column area and prevents liquid from traveling up the shaft.

Bearings – Precision ground, heavy duty grease lubricated bearings are mounted above the coverplate for ease of maintenance and sized to exceed maximum pump loads.

Dual Shaft Seals – Designed to prevent dirt, vapors, and moisture from entering lower bearing area.

Shaft – Heavy duty shaft of high strength materials is turned, ground, polished, and sized with the optimum diameter and bearing span to eliminate deflection problems.

Pump Down Recirculation Line – Creates a liquid seal in the throttle bushing area. This optional service promotes tank pump down capabilities.

Powerframes – Two sizes handle the whole line, which means less parts to stock

Materials of Construction – Pumps are available in all iron, s.s. fitted, 316 s.s., and carpenter 20 construction below the coverplate.
