Description
Overview:
The Pump Diaphragm No. 3 Universal Neoprene is a replacement membrane for diaphragm-type site pumps used for dirty water and general dewatering. Built from tough black neoprene rubber, it flexes repeatedly to create suction and discharge, helping maintain prime and consistent flow. Designed for Hilta and Wacker diaphragm pumps that specify a No. 3 diaphragm, it offers a straightforward swap for a worn or split original part. Key dimensions are a centre hole of 5 in (12.7 cm) and an outside diameter of 13 in (33 cm), matching common No. 3 patterns. Supplied under MPN 836 100, this diaphragm supports reliable operation on site or at home, restoring pump performance without the cost of a full unit replacement.
Key Features:
- Durable neoprene construction for long service life under repetitive flexing
- No. 3 universal pattern suited to many Hilta and Wacker diaphragm pumps
- Centre hole 5 in (12.7 cm); outside diameter 13 in (33 cm) for correct fit-up
- Helps restore suction, prime retention, and overall pump efficiency
- Simple to fit as a direct replacement using existing hardware
- Good resistance to water and general site conditions for dependable use
- Smooth, uniform profile for consistent sealing and reduced wear
- Cost-effective maintenance part to minimise downtime
Typical Applications:
Replacement diaphragm for site dewatering, emptying excavations and trenches, flood and basement water removal, utilities maintenance, landscaping, agriculture, and hire fleet servicing. Ideal where pumps handle dirty water with silt or small solids and require a flexible membrane to maintain steady flow. Suitable for routine maintenance to prevent loss of performance caused by cracking, tearing, or loss of elasticity in the original diaphragm.
