DBY Electric double diaphragm pump
DBY series electric driven diaphragm pump is driven by cycloidal pinwheel reducer and drives the double diaphragm to reciprocate through the crankshaft slider mechanism, so that the volume of the working chamber changes alternately so as to continuously inhale and discharge the liquid. At the same time, in recent years, due to the breakthrough progress made in diaphragm materials, the service life of the diaphragm has been greatly extended, so it is more and more widely used in petrochemical, ceramics, metallurgy and other industries to replace some centrifugal pumps and screw pumps.

Advantage
1. Self-priming performance. The suction lift reaches 3 m height.
2. Wide usage for variety of fluids with high solids cotent. The max grain diameter reaches l0mm.
3. No rotary parts, no mechanical seals, coupling, the diaphragm will completely separate the exhausted medium and pump running parts. Ensures leakless.
4. With explosion-proof electric motor .
5. High viscosity the adhesive liquid(the viscosity is below 10000 centipoise).
6. Available to run dry and no need any lubricant oil.
