Product Description:
The SANDPIPER 286 series pump diaphragms are premium replacement membranes specially engineered for SANDPIPER (Warren Rupp) air-operated double diaphragm pumps. Crafted from high-quality materials such as Red Santoprene, PTFE (Teflon), Neoprene (chloroprene rubber), and PTFE composite with backing, these diaphragms provide exceptional chemical resistance, extended flex life, and dependable sealing performance tailored for the most challenging industrial environments.
Red Santoprene is a superior thermoplastic elastomer that merges the rubber-like flexibility and elasticity with the toughness and manufacturability of thermoplastics. It boasts excellent abrasion resistance, wide chemical compatibility, and a long flex life, which makes it well-suited for handling abrasive slurries and moderate chemical exposures. PTFE, commonly known as Teflon, is renowned as the most chemically inert material available, offering near-universal resistance across a broad pH range from 0 to 14, and it can withstand harsh chemicals and elevated temperatures effectively.
Neoprene, or chloroprene rubber, delivers good resistance to oil, wear, aging, and heat. Its excellent flexibility combined with cost-effectiveness makes it ideal for general-purpose applications involving non-corrosive fluids. In addition, the PTFE composite with backing variant features a PTFE layer bonded to a reinforced substrate, enhancing both durability and chemical protection for demanding service conditions.
Designed for use as original equipment manufacturer (OEM) parts or for routine maintenance, the SANDPIPER 286 series diaphragms ensure precision, reliability, and longevity critical to industrial fluid handling operations. These diaphragms are compatible with a variety of SANDPIPER pumps, including the BQG series and other Warren Rupp air-operated double diaphragm pump models, making them a versatile choice for maintaining optimal pump performance.
Features:
Premium Material Options
We offer an extensive selection of premium diaphragm materials to meet diverse application needs. Our materials include Red Santoprene, PTFE, Neoprene, and PTFE composite with reinforced backing, each designed to provide optimal performance depending on the specific requirements of your operation.
Red Santoprene Diaphragms
Red Santoprene diaphragms combine the elasticity typical of rubber with the durability of thermoplastics. They deliver excellent abrasion resistance, a long flex life, and broad chemical tolerance, making them a versatile choice for many industrial uses.
PTFE Diaphragms
Our PTFE diaphragms offer near-universal chemical resistance across the entire pH range from 0 to 14. They withstand aggressive chemicals and endure high temperatures, ensuring reliable performance in the most demanding environments.
Neoprene Diaphragms
Neoprene diaphragms provide good resistance against oils, wear, aging, and heat, while maintaining excellent flexibility and cost-effectiveness. These properties make them an ideal solution for general-purpose applications.
PTFE Composite with Backing
The PTFE composite diaphragms feature a PTFE layer bonded securely to a reinforced backing. This construction enhances both durability and chemical protection, prolonging the diaphragm’s service life under harsh conditions.
Durability and Design Features
Engineered for superior flex life, these diaphragms can withstand millions of strokes in high-cycling applications. They are available in a wide size range, from ½ inch to 410 millimeters in diameter, accommodating various pump models with precision fit.
Fabric-reinforced construction offers increased strength and pressure resistance, while nylon fabric reinforcement ensures actual service life often exceeds 2,000 hours with over 12 million operating cycles. Each diaphragm is manufactured to exact specifications, especially for the SANDPIPER 286 series and compatible pumps.
