DP type electrical diaphragm metering pump 
Anticorrosive plastic casing 
PTFE diaphragm 
Protection class: IP55 
Pump head: PP, PVC, FTFE, SS316 
Suction and delivery valves: with two balls each one 
Manual control the stroke frequency from 10-100%, LCD displays the normal frequency (at running or stop). 
the start and stop point can be changed and the proportion rate and direction can be changed easily. 
Auto control the stroke frequency by the impulse signal from 0-100%. Can be set 1*N or N/1. (1*N: receive one impulse, the pump runs N times. N/1: receive N impulse, the pump runs once. The scope of N: 1-999.) LED displays the number of N.
