Start with fluid chemistry, viscosity, particle size, required flow and suction conditions. DP-K17 lists 17 L/min maximum delivery and 3/8-inch NPT fluid ports; DP-K40 lists 40 L/min and 1/2-inch NPT ports. Maximum flow is not the delivered flow against every downstream resistance. Confirm wetted materials and diaphragm compatibility, and supply your operating conditions so DINO-POWER can check the selection.

A low-pressure transfer pump does not provide the pressure multiplication of a pneumatic airless piston pump. DINO-POWER DP-K25 lists a 7 bar maximum air pressure and is used in suitable low-pressure fluid-delivery configurations. High-pressure airless spraying needs an appropriate pressure-generating pump and rated accessories. Identify the gun type and required fluid pressure before connecting equipment.

Check air supply, suction leaks, fluid level, strainers, check valves and downstream restrictions. DP-K25 lists 25 L/min maximum delivery, 200 L/min air consumption and a 2 mm maximum grain diameter, but actual performance depends on the application. A larger compressor alone may not correct a blocked fluid path. Isolate supplies and relieve pressure before inspection; use model-matched diaphragms and valve parts.
