Pressure Filters

We also manufacture Flat Bed Multi Plate Pressure Filters for high tech filtration. Dirty fluid is fed under pressure into the inlet manifold. It is distributed equally in 4 different plates. The filter papers are clamped & supported between plates separate the dirt & form a layer (cake). This brings in affect finer filtration. The same filter with pre-coating can add further to fineness of filtration. This is highly suitable as centralized fine coolant filtration for finish grinding, filtration of high viscosity grinding fluids & filtration of honing oil with pre-coat arrangement.

Salient Features:

• Very large filtration area is accommodated relatively small dimensions. The unit shown is having 10 m2 filtration area.
• Totally automatic pneumatically actuated operation.
• Dirt is purged with compressed air to recover fluid.
• Low initial & operational costs.

       
    

We manufacture Pre-Coat Pressure Filters which are designed for easy manual cleaning. Dirty fluid with “filter aid powder” is fed under pressure at the filter inlet so that it forms a uniform layer on the filter discs in the filter shell. During this process the filter outlet fluid is diverted back to dirty fluid tank. This operation is called “pre-coating”. It is performed every-time after the filter is cleaned & put to use again. After pre-coating the filter used to clean the fluid tank. Through separate pump the clean fluid is supplied to the machine. To increase the time of service for the filter a small amount of filter aid powder is fed periodically at the dirty pump suction point. This operation is called “body feeding”. Excellent filtration clarity is generated for high finishing. Once the filter is choked, (usually at pressure drop of 1.5 bar.) the filter housing is drained, purged with compressed air & then opened. The discs are dismantled & cleaned manually using compressed air. Our pre-coat pressure filter give a Super-finishing, finish grinding, honing etc. It can commonly be used for individual machines.

We offer the cartridge type pressure filter which is designed to use the pressure mechanism for filtration. The dirty fluid is pushed in the filter housing under pressure. Filter elements of correct filtration rating are placed in the housing depending on the flow & other requirements. The ends of the filter elements are sealed so that the fluid is made to pass through the filter medium only, to leave the dirt on the filter medium. Generally the inlet and outlet are designed in one line. However the position of the inlet can be altered as per the requirement. It can be efficiently used for a variety of applications depending on the requirement, that is filtration of hydraulic oils, lub oils, fuels, cutting fluids, coolants, washing fluids etc. We also provide a variety of filter elements depending on the fluid to be handled like oils, water based fluids, chemically active fluids washing fluids etc.) dirt to be filtered (from 1 micron till very course mesh type strainers) & type of filtration (disposable elements & re-usable elements). The housing can also be sized depending on the application and the rated flow requirement. Housings of 1, 2, 4, 8, 14 & 24 elements are available. Housings are designed for 10 bar pressure. These can be designed for higher pressures. The housings of verity of material of construction are supplied depending on the requirement.

Salient Features:

• Have unique features making them maintenance friendly.
• Hinged bolts clamp lids.
• Strap clamps are adapted on smaller housings
• Easy to operate lid lifting is for heavier lids.
• Bottom sealing surface for elements is away from filter housing keeping sedimented dirt away.
• This can be removed through the drain arrangement
