Lower Housing Diaphragm Shurflo 94-238-03 Series 2088
Modelo: 94-238-03- Sku: SHURREP008
- Vendor: Shurflo
Specifications
Product Description
The Shurflo 94-238-03 Lower Diaphragm Housing is the original replacement part that forms the base of the diaphragm chamber in Shurflo 2088 series diaphragm pumps. This component is mounted at the rear of the pump head, immediately behind the eccentric diaphragm, creating the pumping volume and ensuring the seal between the hydraulic assembly and the motor. Over time, thermal shocks or improper tightening can deform the housing or damage its seating surfaces, causing internal leaks, noise, loss of flow, and erratic cycles. Replacing it with an OEM part restores factory geometry, reduces losses, and recovers the pump’s smooth and quiet operation.
Main Features
- OEM reference 94-238-03: direct compatibility with Shurflo 2088 series pumps.
- Structural part in contact with the fluid: precision-machined housings and seats.
- High-strength technical plastic material, suitable for potable water and common chemicals.
- Exact factory geometry: ensures correct diaphragm travel and perimeter sealing.
- Plug & play installation: direct replacement using existing screws and seals as per manual.
- Designed for thousands of work cycles with low noise and minimal pressure loss.
Advantages or Benefits
- Restored tightness: eliminates internal micro-leaks that reduce pressure and flow.
- Quieter operation: less vibration and cavitation in the diaphragm chamber.
- Longer service life: the diaphragm operates within its nominal stroke and suffers less fatigue.
- Lower consumption and fewer cycles: the pump does not “hunt” due to leaks, protecting the pressure switch and motor.
- Quick and economical service: simple intervention that avoids replacing the entire pump head.
Purpose or Applications
Professional repair of Shurflo 2088 pumps in motorhomes, boats, homes, light irrigation, reverse osmosis, and cleaning equipment. Especially recommended when there are traces of moisture in the pump head, performance drops, or noise after valve replacement.
