Hydraulic setter of relative pressure ZR-2000

INTRODUCTION:

ZR-2000 type setter is a hydraulic source of a relative pressure. It is driven by hand using the handwheel

The device consists of:

main body with two stub pipes
hydraulic cylinder,
piston with the threaded piston rod
open reservoir with the needle valve connecting to the atmosphere
drive case with handwheel
main stand with fixing holes
needle valves - separate for each stub pipe

The device enables applying the pressure using manual handwheel that does not shift with the movement of the piston along its axis. This saves space in the laboratory as the handwheel can be placed at a short distance from the edge of the table. Threaded part of the piston rod coated with grease is placed inside the device therefore it does not provide any risk of soiling clothes of the operator. All drive elements are covered, so it improves the comfort of the operator.

The device has a lightweight and compact design. Ball bearings used in this device provide a silent, smooth and precise work.
