Wet and Dry Well Submersible
The first Wallwin submersible pumps were sold under license with Robot as Wallwin Robot pumps. Typical model designations were: HW2030-6 and HW3000-4. These were superceded when Biwater acquired the product line and launched a complete range of wet and dry well pumps for both safe and hazardous area operation, typical model designations were; VPFN222-040-4, VP3-110-6. Most parts are still supported from shelf stock with the exception of stator rotors (Brook Crompton). Since 2000, when owned by Gilkes (and up to present now provided by Hydromarque), the submersible range of pumps have been fitted with EMOD motors, which are completely interchangeable with previous models.
