How to choose Merton metering pump, Merton metering pump selection criteria is what?

How to choose Milton's mechanical metering pump for beginners is more difficult, because the market is too much Milton Metering pump, all manufacturers of various brands of products vary greatly, once you choose the inappropriate Milton Metering pump, it will cause damage. How to choose Merton metering pump, Merton metering pump selection criteria is what? 1, Merton metering pump G, B Series product modeling: This selection of information for the required metering pump flow (LPH @ Pmax), pressure (Pmax (bar)), motor power and other information to select the desired metering pump model.
