The only one in the field of “Twin Screw Pumps”!
JRZS series of Twin-Screw Pumps were newly developed with very unique “One piece with large radius corner screw case” design, very compact “Front loaded self-balanced mechanical sealing system”, “Fully drainable front cover” and “Integral geared adaptor with B5, 4pole motor directly coupled”. It is the only one in field of the “Twin Screw Pumps”!

The JRZS series were designed for reliable pumping from low to high viscous, volatile or gaseous products and applications to fulfill the utmost hygienic and efficiency requirement produced according to the highest hygienic specifications such as EHEDG & 3-A certified manufacturing processes.

JRZS Series

Integral Type

The cutting edge of Twin Screw Pumps, JRZS series can be supplied diverse types to meet the customer’s requirements. The standard type of JRZS Series, the ‘Integral type’ consists of integral geared adaptor with B5, 4 pole motor directly coupled. This provide the most cost & space effective due to the size of 4P motor and higher efficiency instead of coupled with 6P or 8P motors and convenient to get with quick delivery.

And also can be supplied as a ‘Bare shaft’, i.e. pumps head only without motor or common bed. Or, can be supplied as a ‘Complete unit’ with drive (geared motor), coupling & guard, common bed.
