a built-in inlet anti-suckback valve that prevents the pump from rotating backwards when shut down with vacuum remaining in the process and prevents the rotor housing from flooding with oilĪt a given temperature, vapor may be compressed only as far as the saturation vapor pressure beyond that point, the vapor condenses.an automotive spin-on oil filter (on larger sizes).Oil is then returned to the oil reservoir.įeatures of the DEKKER Vacuum rotary vane pumps include: See #3 in the diagram below.Īir then passes through several stages of internal oil-and-mist eliminators to remove 99.9% of the lubricating oil from the exhaust. Air is compressed and discharged into the exhaust box as rotation continues. Since the rotor is located eccentric to the pumping chamber, the volume between the rotor, vanes and housing decreases and increases rotor spins. This creates increasing cell volume on the inlet port side, creating vacuum. As the pump rotor turns, inlet air is trapped between the rotor and vane segments (see #1 in the diagram below). The pump rotor is mounted eccentrically in the pump cylinder. The construction is heavy-duty and compact. The standard lubricated rotary vane pump is a single-stage pump with an integral, closed-loop oil-circulation system.

One such advancement is the Automatic Knife Advance System (AKAS) which is used to optimise precoat usage on a rotary drum vacuum filter.įiltration Services offer bespoke manufacture and design of the rotary drum vacuum filter to meet both your site-specific requirements and the exacting standards of today’s industry.

It is also available in wide range of sizes and choices from lab and pilot scale to full production scale.įiltration Services Ltd is at the forefront in the design and manufacture of rotary drum vacuum filters and has developed advancements which have improved efficiency and helped in reducing costs. The rotary drum vacuum filter is a versatile filter that is reliable, continuous and requires minimal operator effort/attention. The rotary drum vacuum filter is used for a number of different applications such as the filtration of bulk or fine chemicals, pharmaceuticals, pigments, foods, bulk minerals, sludge dewatering, wastewater treatment, and biofuels. The basic principle of the rotary drum vacuum filter has been around for over 100 years and is one of the oldest types of filters used for solid and liquid separation.
