Macnaught Air Operated Diaphragm Pump - 1 1/2" DDP38

Air Operated Diaphragm Pump - 1 1/2" The Macnaught DDP38 offers an economical and reliable pump for transferring light to medium viscosity fluids. High flow rates can be achieved easily, particularly in low back-pressure applications. The pump is capable of safe dry-running for simple self-priming without damage. Featuring a robust cast aluminium body, the DDP38 is compatible with a wide range of chemicals, making it suitable for oils (new & used), engine coolants (RTU), diesel, and oily water applications. Fully repairable with spare parts readily available. (Not suitable for flammable liquids.) FEATURES Up to 265 L/min flow rate, measured at the pump outlet with water Fitted with band clamps on inlet and outlet manifolds for easy dismantling, repairs, or clearing blockages Cast aluminium body for wide chemical compatibility across multiple applications Air-operated design allows speed control for adjustable pump output Cost-effective solution for fast transfer of low to medium viscosity fluids Easy self-priming and dry-run safe for short periods without damage SPECIFICATIONS Maximum air pressure: 690 kPa (100 psi) Inlet / outlet ports: 1½" BSP(F) Air inlet size/type: 1/2" NPT(F) Maximum flow rate: 265 L/min (viscosity dependent) Suction lift: 4.6 m (dry), 7.6 m (wet) Maximum solids handling: 4.76 mm (0.188") Fluid temperature range: -12°C to 82°C Maximum noise level: 77 dB(A) Fluid compatibility: oils (new & used), engine coolants RTU (new & used), oily water, diesel Wetted components: cast aluminium (body), Buna N (valve seats, diaphragms, check valves) PACKAGE INCLUDES Macnaught DDP38 1½" air-operated double diaphragm pump Air exhaust muffler 3/4" NPT(M) Instruction manual
