Uni-Lok Zero

 Technical Data: 

Patented CP barrier fluid reservoir that takes peak discharge reference pressure and adds 24 to 41 psi (1.8 to 2.8 Bar) to the barrier fluid

References only the peak discharge pressure from the discharge line of the pump

Accomplished without the need for external nitrogen gas supplies, external pumps, power supplies or bladder accumulators

Modified stuffing box arrangement to accommodate the reverse pressure sealing

Patented spring loaded pressure addition system 

 Uni-Lok Zero   
  
   
Key Applications: 

 

Prevents leakage out of the pump through the stuffing box
 
  
Ensures that reciprocating pumps can meet the EPA VOC fugitive emissions compliance values  
  
Extends or maintains high packing life extended by 5 years 
  
Can be fitted to new or existing machines
 
Description:

The UNI-LOK® Zero sealing system, dramatically reduces VOC fugitive emissions to the atmosphere from reciprocating pump stuffing boxes, significantly extending the seal life achieved through this unique stuffing box. This innovation incorporates a device that references the peak discharge pressure from the pump and a reservoir that delivers a pressurised barrier fluid to the stuffing box, forcing leakage inward rather than allowing outward flow through the seals.

The UNI-LOK® Zero System is available for both new equipment and as an aftermarket retrofit to provide unparalleled protection from VOC emissions to comply with current and future environmental standards.
