The SP-SS40-FL304 is a compact, air-operated double diaphragm pump (QBY-15Z series) designed for safe, efficient transfer of low-viscosity fluids in demanding industrial environments. Powered by compressed air (no electrical power needed), it features a sturdy cast iron body with plastic spraying for corrosion and wear resistance. Ideal for handling water, glue, water-based coatings, organic solvents, and low-viscosity petroleum fluids like diesel, kerosene, motor oil, or waste oil.
Double diaphragm design ensures reliable, leak-free operation even with abrasive or shear-sensitive fluids. Not suitable for strong acids, alkalis, or highly corrosive liquids – always check compatibility.
Flow rate up to 4.4 GPM with adjustable air pressure; max head 164 ft and suction lift 16.4 ft make it versatile for transfer, filling, or circulation tasks.
Typical Diaphragm Pump Performance

Adjustable via air supply pressure – ideal for precise control in chemical and petroleum applications.
Q: Is this pump suitable for corrosive liquids? A: No – not for acids, alkalis, or strong corrosives. Best for low-viscosity petroleum fluids, solvents, water-based coatings, etc.
Q: Does it require electricity? A: No – fully pneumatic (air-operated). Requires clean compressed air supply (1/4" inlet).
Q: Can it run dry? A: Yes – diaphragm pumps tolerate dry running better than many centrifugal types, but monitor air consumption.
High-flow centrifugal pump – for larger industrial & chemical applications.
