GRACO 24B781 - Husky 1590 SS Pump AL Center Section SS Seats PTFE Balls & PO Diaphragm
Industrial pump component featuring aluminum construction with stainless steel seats and PTFE balls for reliable performance in demanding industrial applications. Part of GRACO's Husky pump series designed for consistent fluid handling.
The Husky 1590 air-operated diaphragm pump features a patented, high-reliability closed center air valve that is online serviceable and an epoxy-coated air section for tough environmental conditions.
- Up to 5 times longer diaphragm life compared to other air operated diaphragm pumps in its class
- Expanded material offering to handle endless applications
- Fewer parts than industry peers, the air valve is externally accessible so it can be serviced quickly and easily without uninstalling the diaphragm pump
- Offered in ATEX configuration.
- 1-1/2 in. (38.1 mm) ANSI end-porting
- High flow - 100 gpm (378 lpm) in a compact, portable size
- Fluid pressure to 120 PSI (8.4 bar, 0.84 MPa)
- Lube-free operation
- Available in polypropylene, aluminum and stainless steel
- Epoxy-coated air section for tough environmental conditions
