choice of hydraulic double plunger continuous screen changer series: 

The selection of a new type of screen changer filter should be selected based on several factors such as materials, product types, production volume, material pressure in the system, and degree of automation.

The general principle is: high product quality, high production efficiency, long production process, high degree of automation, choose non-stop continuous screen changer, can replace the filter without interrupting the product, increase production, save energy, easy to operate, and no waste.

The production process is short, the degree of automation is low, and the product quality requirements are not high. You can choose a fast non-stop screen changer. The quick screen changer saves time, is low in price and saves investment.
