Key specifications

Selecting the right option

Select by port size (1/2", 3/4", 1", 1½", 2", 3") based on required flow rate and pipe connection. Larger ports deliver higher flow — confirm the air supply can meet the pump's air consumption at your target flow rate. Tank-mounted diaphragm pump combinations (OTL-DP range) are available in 700L, 1000L and 1500L storage capacities. Contact AIMS for fluid compatibility and material selection guidance.
