Pre-Coat Pressure Filters

Standard filter are not able to provide very fine filtration of 1 micron or lesser is required. In such cases precoat filter is used. Precoating is a process of adding a graded powder to form a layer on the standard filter media. The layer provides a larger surface area which in turn increases the dirt holding capacity. It also generates a toroidal path for the fluid, thereby entrapping the finer particles.

Precoat powder is added in controlled measure based on your application.
Clean fluid is supplied to the machine after the precoating cycle is complete.
A separate clean tank provides clean fluid to your machine while the indexing process is going on.

Dirty fluid is fed under pressure in to inlet manifold. It is distributed equally in plates. Filter papers clamped & supported between plates separate the dirt & form a layer (cake). This effects finer filtration. Differential pressure is monitored in inlet and outlet manifold. At a preset level, the indexing cycle starts. First the inlet actuated valve is closed. Compressed air is pushed in the inlet manifold to remove the fluid inside the plates. This also purges the filter cake and makes it dry. Then with help of hydraulic or pneumatic cylinders the top plate is opened. A geared drive moves the belt which is supporting the filter cake. Once the complete filter cake is pulled out, the top plate closes and inlet actuated valve is opened. Normal filtration process begins again.

Client Speak

Maruti Udyog Ltd.

We installed Veeraja's Filtration System (vacuum filter, scraper conveyor, upflow drum) for honing machine. Initially we tried on one machine & with satisfactory results implemented on 3 machines. The results were fantastic. The filtration level was very good, sorted out issues on honing tool jamming issues, size variation due to improper filtration. Appreciate Veeraja teams support for appropriate, cost effective solution, understanding our pain & resolving the same.

Mr. Prasad Shirodkar

Plant Head, Gabriel India Limited.

We installed Veeraja's Centralized Filtration System (vacuum filter, scraper conveyor, upflow drum) for grinding line and deep hole drilling a few years ago. We were convinced that results would be positive and am glad to announce that our projections were correct. Productivity increased through recycling, lowering electricity bills and improved cycle times on processes. Great investment, great ROI

Mr. Nikhil Patani

GM, BD & Projects, Precision Camshafts Ltd.

We installed Veeraja's Centralized Filtration System (vacuum filter, scraper conveyor, upflow drum) for grinding and machining. Our productivity inproved substantially, lowering power supply cost and improved cycle times on processes. Working with Veeraja Industries was a pleasant experience. Very happy. Keep up the good work Veeraja Industries. Profitable investment for our business division.

Mr. Ajitkumar Jain

Also they offer the widest range of technologies to choose from. Low operations cost is another important benefit the user gets. I strongly recommend filtration solutions from Veeraja Industries.

Mr. Hemantkumar Tambade

Managing Director, NHB Ball & Roller Ltd

Working with Veeraja Industries was a pleasant experience. Work was completed on time and within our stipulated budget range. Happy overall.

Mr. Kalpesh Mehta

When we were setting up one of our plants, the Management decided to Install Centralised Filtration System for Process media like Coolant, Honing / Lapping Oil. We reviewed lot of providers but ultimately entrusted Veeraja Industries to engineer Centralised Filtration System. We were convinced that results would be positive by Productivity increase through recycling of Coolant, Honing / Lapping Oils, lowering electricity bills and improved cycle times on processes due to Clean Coolant, Honing / Lapping Oils. Great investment, great ROI. Profitable investment for any business division as the functional results are wonderful.
