Low Pressure Filter Press Model ZNS-5A
|Maximum cup pressure|
|Effective filtration loss area|
Model ZNS-5A and Model SD6A Low Pressure Filter Press is used for measuring filtration and wall-building properties of drilling fluids and cement slurries. The filtration rate is the fluid loss measured in milliliters at ambient temperature and 0.69MPa through a special filter paper for 30 minutes. Wall -building characteristics are demonstrated by the thickness and consistency of the filter cake (the residue) deposited on the filter paper after 30 minutes. The filter cake is measured to the closest 1/32 in. or the nearest millimeter.
The low pressure filter press assemblies described in this manual consist of the following items:
1.filter cell mounted in a frame
2.pressure assembly and regulator
3.filter paper, the filtering medium
4.25 ml graduated cylinder, the filtrate receiver
The filter press cell body, top cap, and base cap are constructed of stainless steel.
The filtering medium is filter paper that has been especially hardened for filtrate testing.
Multiple Unit Filter Press assemblies permit simultaneous running of one to six filtration tests. Each one of the assemblies consists of a frame with the indicated number of complete Stainless Steel filter cells. Manifolds are complete with air hoses, cut-offs and bleeder valves.
Compressed oxygen should not be used as a pressure source. Fire and explosion hazards exist when using oxygen.
