Reliable transfer, easy service, lower running cost
Husky™ pumps are built to get the job done every time and to keep running cheaply. Rugged construction resists corrosion for long life in harsh sea conditions; diaphragms are rated to last five times longer than others in their class; and the complete air valve is externally accessible, so the crew can service it fast without removing the pump. Where air supply is short, the electric 1050e delivers the same self-priming, stall-under-pressure behaviour while cutting energy use up to 5×.
- ATEX 316 SST builds for chemicals & petroleum in classified zones
- Self-priming, run-dry safe, stalls under pressure against a closed valve
- Stall-free, low-pulsation modular air valve; Smart valve on larger models
- Diaphragms and air valves serviced in place with modular repair kits
