Product Description:
SANDPIPER 286 Series Pump Diaphragms
The SANDPIPER 286 series pump diaphragms are premium replacement membranes specifically engineered for SANDPIPER (Warren Rupp) air-operated double diaphragm pumps. Crafted from top-grade materials such as Red Santoprene, PTFE (commonly known as Teflon), Neoprene (chloroprene rubber), and PTFE composite with backing, these diaphragms offer outstanding chemical resistance, extended flex life, and dependable sealing performance even under the most rigorous industrial conditions.
Red Santoprene is a high-performance thermoplastic elastomer that merges the flexibility and elasticity of rubber with the toughness and processing advantages of thermoplastics. It boasts excellent abrasion resistance, wide-ranging chemical compatibility, and a long flex life, making it a perfect choice for handling abrasive slurries and moderately aggressive chemicals.
PTFE, or polytetrafluoroethylene, is renowned for being the most chemically inert material available. It provides nearly universal chemical resistance across the entire pH scale from 0 to 14, and can endure exposure to aggressive chemicals as well as elevated temperatures with ease.
Neoprene (chloroprene rubber) offers robust resistance to oils, wear, aging, and heat, alongside excellent flexibility and cost effectiveness. This combination makes it an ideal option for general-purpose applications involving non-corrosive fluids. The PTFE composite diaphragm variant features a bonded PTFE layer attached to a reinforced backing, delivering increased durability and enhanced chemical protection.
Whether utilized as original equipment manufacturer (OEM) replacements or for routine maintenance purposes, SANDPIPER 286 series pump diaphragms ensure the precision, reliability, and longevity essential to critical industrial fluid handling operations. These diaphragms are compatible with SANDPIPER pumps including the BQG series and a variety of other Warren Rupp air-operated double diaphragm pump models.
