subject: Pressure Filter [print this page] We are one of the well-known manufacturers and suppliers of a wide range of Filters and Pressure Filter Housing. In our range, we offer Hydraulic Filter, Vacuum Filter and Pressure Filter Housing. These are manufactured using quality components to ensure high efficiency and longer service life. Offered in various technical specifications, these can be availed by our clients at competitive prices.
Pressure Sand Filter consists of a pressure vessel-this could be either vertical or horizontal-fitted with a set of frontal pipe work and valves, graded silica quartz sand supported by layers of graded under bed consisting of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to collect filtered water.
Raw water flows down wards through the filter bed and as the suspended matter- which has usually been treated by addition of a coagulant like alum- is retained on the sand surface and between the sand grains immediately below the surface. There is steady rise in the loss of head as the filter process continues and the flow reduces once the pressure drop across the filter is excessive.
Pressure Filter
In difficult drainage environments, where you want to spread the effluent out as much as possible to ensure you do not clog your media, this filter will act as a second level of filtration and will keep orifice lines clean.
Features
1. Mounts directly onto the discharge end of any pump. No extra plumbing is necessary!
2. Filters available in heavy duty stainless steel or reinforced plastic. Filters can use a 300 micron sock for fine filtration.
3. Twist & Lok cover provides both watertightness and easy access for filter maintenance.
4. Extension handle is available for deep installations.
Ideal for:
- Filtering solids before they reach the drain field.
- Advanced systems.
- Pressure dosing systems.
- Poor soil conditions.
pressure filter holders are ideal for filtering gasses or liquids. Our large standard stainless steel pressure filter holders allow you to seal the membrane by hand with tightening and locking wing nuts. The large sanitary stainless steel large filter holders are non-threaded and can be completely disassembled for more thorough cleaning. Choose one of our reservoir filter holders for filtering small batches of liquid without having to use a separate Pressure Filter vessel. We even carry multi media pressure sealing filter holders with a dual sealing system that compresses the filter between the inside wall and O-ring on the outer edge.
Designed for use as full-flow or partial flow filters and for the low pressure range up to 25/60 bar, medium pressure up to 210 bar and high pressure up to 450 bar, MAHLE pressure filters are ideal for application as main-line filters, flangemounted filters and filters in intermediate plate design. Rugged casings, streamlined design and an extensive range of accessories provide the optimal solution capable of meeting every market requirement.

Multigrade Sand Filter
Multigrade Sand Filter also consist of a vertical or horizontal pressure vessel with a set of frontal pipe work and valves, media consist of different sizes and grade mixed and supported by layers of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to collect filtered water.
This filter performs at a substantially higher specific flow rate than conventional filters. The basic difference between Pressure Sand Filter (PSF) and Multigrade Sand Filter (MGF) are media used in vessel and velocity variation.
