Product Description:
The SANDPIPER 286 series pump diaphragms are premium replacement membranes engineered specifically for SANDPIPER (Warren Rupp) air-operated double diaphragm pumps. Crafted from high-grade materials such as Red Santoprene, PTFE (Teflon), Neoprene (chloroprene rubber), and PTFE composite with backing, these diaphragms provide outstanding chemical resistance, extended flex life, and dependable sealing performance to meet the challenges of the most demanding industrial environments.
Red Santoprene is a high-performance thermoplastic elastomer that merges the flexibility and elasticity of rubber with the durability and processability typical of thermoplastics. This material offers superior abrasion resistance, wide-ranging chemical compatibility, and a long flex life, making it an excellent choice for handling abrasive slurries and a variety of moderate chemicals. On the other hand, PTFE (polytetrafluoroethylene), widely known as Teflon, is renowned for its exceptional chemical inertness. It delivers nearly universal chemical resistance across the entire pH spectrum from 0 to 14, and it can withstand exposure to aggressive chemicals and elevated temperatures.
Neoprene, or chloroprene rubber, is prized for its balanced combination of oil resistance, wear resistance, aging resilience, and heat tolerance. Its flexibility and cost-effectiveness make it well-suited for general-purpose applications involving non-corrosive fluids. Additionally, the version made with PTFE composite backing incorporates a PTFE layer bonded to a reinforced backing, which enhances both durability and chemical protection, ensuring longer service life under harsh conditions.
Whether deployed as original equipment manufacturer (OEM) replacements or used during routine maintenance schedules, the SANDPIPER 286 series pump diaphragms deliver the precision, reliability, and durability essential for critical industrial fluid handling operations. These diaphragms are compatible with various SANDPIPER pumps, including the BQG series and other Warren Rupp air-operated double diaphragm pump models.
Features:
We offer a variety of premium material options to meet diverse application needs. These include Red Santoprene, PTFE, Neoprene, as well as PTFE composite materials with backing, ensuring compatibility with different operational requirements.
Red Santoprene diaphragms combine the elasticity of rubber with the durability of thermoplastics. They provide outstanding abrasion resistance, extended flex life, and a wide range of chemical compatibility, making them suitable for demanding environments.
PTFE diaphragms are designed to deliver nearly universal chemical resistance across the entire pH range from 0 to 14. They are capable of withstanding harsh chemicals and elevated temperatures, offering reliable performance in challenging conditions.
Neoprene diaphragms are recognized for their excellent oil resistance, wear resistance, and aging resilience. They also maintain good heat resistance while offering flexibility and cost-effectiveness, making them ideal for general-purpose uses.
The PTFE composite diaphragms feature a PTFE layer bonded to a reinforced backing. This construction enhances both durability and chemical protection, providing a robust solution for demanding applications.
All diaphragms are engineered to deliver superior flex life, capable of enduring millions of strokes in high-cycling scenarios. This ensures longevity and reliable operation in continuous-use environments.
Our product range covers a wide variety of sizes, with diameters ranging from 1/2 inch up to 410 millimeters. This extensive size selection guarantees compatibility with numerous pump models.
