Graco D52977 Husky 515 Air-Operated Diaphragm Pump – Industrial Fluid Transfer Solution
The Graco D52977 Husky Pump, 515P-PP01AP3PPBNBNPT0 is a compact, air-operated double diaphragm (AODD) pump designed for reliable fluid transfer in industrial environments. Built with a polypropylene fluid section, PTFE sealing components, and Buna-N diaphragms and balls, it delivers consistent performance for handling a wide range of compatible fluids with moderate chemical resistance and low maintenance requirements.
Compatible Machines / System Applications
- Industrial Fluid Transfer Systems – Used in general manufacturing lines requiring safe, low-pressure fluid movement.
- Paint & Coating Circulation Units – Suitable for low to medium viscosity coatings and primers.
- Chemical Handling Skid Systems – Compatible with polypropylene-based chemical dosing and transfer setups.
- Spray Equipment Supply Pumps – Supports air-powered spray systems requiring steady fluid delivery up to 15 GPM.
- OEM Equipment Integration – Commonly installed in original equipment manufacturer (OEM) fluid handling assemblies using 1/2" NPT porting.
This pump is widely used in systems that require air-driven, non-electric pumping with safe operation in potentially hazardous or moisture-prone environments.
What is Graco D52977 Husky Pump, 515P-PP01AP3PPBNBNPT0?
The Graco Husky 515 D52977 is a non-metallic pneumatic diaphragm pump designed for transferring fluids using compressed air instead of electric motors. Its bolt-through fluid cover design reduces leakage risks, while the stall-free air valve system ensures smooth and efficient fluid displacement.
It is engineered for industrial reliability, offering up to 15 GPM (56.7 L/min) flow rate, operating at up to 100 psi fluid pressure, and handling small suspended solids, making it suitable for continuous-duty applications.
Key Construction Features
- Polypropylene body for chemical resistance and lightweight durability
- Buna-N diaphragms and check balls for flexible fluid handling
- PTFE O-rings for improved sealing integrity
- 1/2" NPT ports for standard industrial connectivity
Frequently Asked Questions
It is an air-operated double diaphragm (AODD) pump that uses compressed air to move fluids without electric motors, making it safe and versatile for industrial environments.
The pump features a polypropylene housing, Buna-N diaphragms and balls, and PTFE sealing components, providing balanced chemical resistance and durability.
The Graco Husky 515 D52977 delivers up to 15 gallons per minute (GPM), depending on fluid type, air pressure, and system configuration.
Yes, it is suitable for mild to moderately aggressive chemicals that are compatible with polypropylene and Buna-N wetted materials. Always verify chemical compatibility before use.
No. The pump runs entirely on compressed air, making it ideal for hazardous or explosion-sensitive environments where electric motors are not suitable.
