Packo ZS Twin Screw Pumps

The ZS series can be supplied in diverse types to meet the customer’s requirements. The standard type of ZS Series, the ‘integral type’ consists of integral geared adaptor with B5, 4 pole motor directly coupled. This provides the most cost & space effective solution, due to the size of 4P motor and higher efficiency instead of coupled with 6P or 8P motors and convenient to get with a quick delivery time.
