Wallwin Dry Well Pumps

Many thousands of Wallwin Pumps have been supplied to Local Councils, Water Companies and general industry since the 1920’s and this proven design is still available today. Early models were supplied with packed gland sealing arrangement with current models being fitted with cartridge type mechanical seals. Retrofit kits are available to convert from packed glands to mechanical seals. Typical model designations are: 1090, 1094, 4S, 4X & 6S. All parts are fully supported and most available from shelf stock. New replacement pumps are available and built from stock to ensure a short lead time.
