1 Inch 15R022 24B628 Blue Santoprene Replacement Diaphragms for Graco 1050 Pneumatic Diaphragm Pump

The Graco Husky Series air-operated double diaphragm (AODD) pumps represent leading-edge technology in fluid transfer solutions. These pumps are designed with a focus on reliability, operational efficiency, and minimal maintenance requirements. Available in a variety of sizes from 3/8″ to 3″, the Husky series accommodates flow rates ranging between 7 gallons per minute (GPM) and 260 GPM. This versatility makes them an excellent choice for applications that span from light chemical dosing to heavy-duty industrial fluid transfer.

Central to the performance of every Husky pump is its diaphragm system, which comes in several material options tailored to meet diverse fluid compatibility needs. Materials available include PTFE (Teflon®), Santoprene™ (GE – Graco Engineered Thermoplastic), Nitrile (Buna-N), and Viton® (FKM). To facilitate maintenance and ensure dependable operation, Graco provides both individual diaphragms and comprehensive fluid section repair kits. These kits contain all essential components such as diaphragms, balls, seats, O-rings, and center shafts, enabling a complete and reliable rebuild of the pump’s fluid section.

The Husky series incorporates several key innovations that set it apart in the market. Among these are stall-free low pulsation air valves that ensure smooth and rapid changeovers during operation. Additionally, the pumps feature one-piece center sections that help eliminate air leaks while reducing maintenance demand. Users benefit from diaphragm lifespans that are up to five times longer than those found in comparable AODD pumps. Select models also deliver efficiency improvements of up to 40%. Moreover, the air valves are designed to be serviceable externally, which means there is no need to uninstall the pump for maintenance, enhancing overall convenience and uptime.

The Stall-Free Low Pulsation Air Valve ensures smooth and rapid changeover, significantly reducing fluid shock and extending the diaphragm's lifespan. This feature enhances the overall efficiency and durability of the pump.

The one-piece center section design eliminates air leaks, promoting more efficient operation and simplifying maintenance tasks. Additionally, the four-bolt fluid cover joint design delivers even sealing pressure, ensuring leak-free performance throughout the pump's lifecycle.

Unlike other pump types, these pumps have no mechanical seals, which removes a common point of failure. They operate quietly at less than 85 dBa, with the option for a remote muffler to achieve even lower noise levels. Multiple porting options, including center and end port configurations, provide installation flexibility.

Certified with ATEX and CE standards, these pumps are suitable for use in hazardous environments. Furthermore, their lube-free operation reduces maintenance needs while eliminating the risk of oil contamination.

PTFE (Teflon®) diaphragms offer excellent chemical resistance, making them ideal for handling aggressive solvents, acids, and caustics safely and efficiently.

Santoprene™ (GE) diaphragms are engineered thermoplastics by Graco that provide outstanding wear resistance and flexibility, making them suitable for a broad range of general-purpose applications.

Nitrile (Buna-N) diaphragms deliver superior resistance to oils and fuels, ensuring durability in demanding environments. Some models feature two-piece PTFE/EPDM diaphragm designs, combining chemical resistance with enhanced flexibility.

Overmolded diaphragm designs extend service life and improve sealing performance, contributing to overall pump reliability.

The complete fluid section rebuild kits include essential components such as diaphragms, balls, seats, O-rings, and the center shaft where applicable, facilitating thorough maintenance.

All kits utilize genuine OEM parts made from factory-specified materials, ensuring proper fit and maximizing service life. Additionally, application-matched materials are available, allowing selection of kits tailored to specific fluid compatibility requirements.

The chemical processing industry involves handling a variety of substances such as acids, caustics, solvents, and other aggressive chemicals. These materials require specialized equipment designed to withstand their corrosive nature and ensure safe transfer.

In the field of oil and fuel transfer, common fluids include motor oil, hydraulic fluid, diesel, and various fuel oils. Efficient and reliable pumps and transfer systems are essential for managing these substances to maintain operational safety and effectiveness.

Automotive and workshop environments deal with fluids like antifreeze, windshield washer fluid, gear oil, and coolants. Proper fluid management in this sector helps in maintaining vehicle performance and prolonging equipment life.

Industrial manufacturing often requires the transfer of water and wastewater, detergents, and various process fluids. Equipment used here must cater to diverse applications and handle fluids that may vary in chemical composition and temperature.

The mining and construction industries handle challenging liquids such as slurries and abrasive fluids, as well as dewatering applications. Robust and durable fluid handling solutions are necessary to operate efficiently under these harsh conditions.

Within the food and beverage sector, sanitary fluid transfer is critical. Select stainless steel models are employed to ensure hygiene and prevent contamination during the transfer of food-grade liquids.

In the pharmaceutical industry, the transfer of pure chemicals requires equipment with PTFE wetted parts to maintain purity and avoid any chemical reactions. This ensures the integrity of pharmaceutical products throughout the manufacturing process.

Agriculture demands the handling of fertilizers, pesticides, and liquid feed. Specialized fluid transfer solutions support efficient distribution and application of these agricultural chemicals to enhance crop production.
