USUN Model:ZB10 Middle Size 10：1 Ratio Driven Air Driven Liquified Gas Or Refrigerant Pumps for Recovery Or Filling Tanks

Usun Model :ZB10  160 MM driven air driven liquified gas or refrigerant pumps for recovery refrigerants

ZB series of liquid pumps are unique in the USUN range as they use pistons rather than plungers in the liquid ends.

This enables them to achieve high pressure fluid outlet flows in both directions of the reciprocating pump action, 

making them double acting and very efficient. All ZB Series pumps are suitable for liquids, gases and vapours. 

They are also capable of drawing a vacuum down to 11.25 psi(absolute) in the 2-stage configuration.

Key features

1. Effieciency - Pump the liquid first...then the vapor... Then vacuum to 23-27 degrees with one pump

2. No heat,flame or spark risk

3. Infinitely variable cycling speed and output

4. Air driven Models do not require electrical connection ,easy to apply automatic controls

5. No limit or adverse affect to contineous stop/start applications

6.Seals system designed for long working life,No airline lubricated required

7. Cool operation : No heat generated during liquid transfer .Minor warming during vapor transfer .No

Refrigerant heating from the motor

Main technical data  

Remark 1) Maxium outlet pressure are at an air driven pressure of 8 bar or 116 PSI ,for long life using

of such pump ,we suggest that air driven pressure should be not more than 8 Bar  .
