The Graco 651119 Husky 1050S-PA01DS1SSSSBNPT Pump is designed as a standalone, air-operated diaphragm pump. It does not mount into a single dedicated machine but integrates seamlessly into a wide range of industrial systems using standard 1-inch NPT fluid connections and compressed air supply.
Product Overview
The Graco 651119 Husky 1050S is a 1-inch air-operated double diaphragm pump engineered for reliable fluid transfer in demanding industrial environments. Its stainless-steel construction and PTFE internal components make it suitable for handling aggressive, corrosive, and high-purity fluids with consistent performance.
- Air-operated double diaphragm (AODD) design for safe use in hazardous areas
- Stainless steel fluid sections for corrosion resistance
- PTFE diaphragms and balls for chemical compatibility
- 1″ NPT inlet and outlet ports for easy system integration
- Self-priming capability with reliable suction lift
- Handles abrasive and solid-laden fluids within operating limits

Frequently Asked Questions
This pump is not a direct replacement for airless spray pumps. It is commonly used as a fluid supply or transfer pump feeding paint, coatings, or solvents to spray systems or circulation lines.
Yes. The stainless-steel fluid sections and PTFE internals provide excellent resistance to a wide range of corrosive and aggressive fluids.
No. The pump operates entirely on compressed air, making it suitable for environments where electrical equipment is restricted or unsafe.
