1 Inch Air r-Operated DoubleDiaphragm Pump, Aluminum Alloy PTFE Industrial Pneumatic Transfer Pump 35GPM 120PSI, for Low Viscosity Fluid, Oil, Diesel, Colorant (QBY4-50 Aluminum +PTFE 172GPM)

This heavy-duty pneumatic diaphragm pump is specifically designed for harsh industrial environments, enabling leak-free and highly reliable fluid transfer. Featuring a robust aluminum alloy pump and a reinforced diaphragm design, it can stably transport corrosive, high-viscosity, or particle-containing media, making it an ideal choice for applications such as chemical processing, manufacturing mining, and wastewater treatment.

• PNEUMATIC DOUBLE DIAPHRAGM PUMP——The diaphragm pump housing is made of aluminum alloy and fixed with a fully bolted structure to ensure a secure connection between all components, thereby achieving first-class sealing performance. It combines the reciprocating motion of rubber, thermoplastic, or Teflon diaphragms. The upper and lower inlet/outlet pipes are equipped with 4 check valves. When the pump stops or there is a short interruption in air supply, the ball valves close automatically to lock the medium in the pump chamber, preventing backflow and allowing the pump to self-prime smoothly upon restart.
• PARAMETER——35 GPM pneumatic double diaphragm pump, inlet and outlet size 1 inch. Air tube thread 1/4 inch connected to 8mm outer diameter air tube, maximum particle size 3.2mm. This powerful pneumatic double diaphragm pump has an operating pressure range of 29 to 115 PSI. Maximum temperature: 150°F/66°C; maximum pressure: 120 psi; maximum flow rate: 35 GPM; maximum head: 226.38 feet/69 meters. Can pump at a flow rate of 35 gallons per minute at temperatures up to 80 degrees Fahrenheit.
• ADVANTAGES—— No lubrication required, capable of dry running, no damage to the pump if no liquid is sucked in, fully driven by compressed air, no motor no electric sparks, fully suitable for highly flammable, explosive, and high-dust risk environments, eliminating the risk of overheating. Flow rate and head can be adjusted via valve switches suction volume can be adjusted via pressure, capable of working submerged in the medium, can pump both high-viscosity and low-viscosity liquids, low energy consumption, and low consumption. Simple structure with few moving parts, significantly reducing wear and tear.
• APPLICABLE LIQUIDS——non-strongly corrosive, conventional fresh water, oil products, ordinary slurries; can transport: fresh water, river water, seawater, industrial circulating water, ordinary sewage, diesel, gasoline, engine oil, lubricating oil, hydraulic oil, cutting fluid, emulsion, thin slurry, ordinary coatings, weakly alkaline fresh water, neutral saline wastewater.
• PROHIBITED LIQUIDS——strong acids, strong bases, strong solvents, corrosive media. Practical tips: To ensure optimal performance, please use filtered and lubricated compressed air, and select the appropriate diaphragm material based on the conveyed medium (PTFE for strong acid media, EPDM for general aqueous media).
