FGP – CERAMIC LIQUID RING VACUUM PUMP

THE SOPHISTICATED PUMP CONCEPT

LIQUID RING PUMP WITH OUTSTANDING RELIABILITY
Our FGP liquid ring pump is the suitable partner for difficult evacuation and compression processes involving gases and vapours in all corrosion-critical areas of application in the chemical industry. Together with the freely selectable operating medium of the liquid ring, the FGP allows volume flows of up to 700 m3/h. In compressor mode gas pressures of up to p2 max = 2.5 barg are easily created. In vacuum mode for aggressive media the pump produces suction pressures of p1 = 100 mbara up to p1 = 25 mbara with an additional gas ejector. And this all takes place at gas temperatures of up to 120 °C.

SAFE CONCEPT FOR TOUGH ASSIGNMENTS
Manufactured from solid and gas-tight silicate ceramic FRIKORUND®, the FGP is ideally suited to all media which contain i.e. chlorine or hydrogen chloride. The valveless working principle of the pump promises a high level of safety in critical, multi phase applications – with compression processes of ignitable gases and vapours up to explosion zone 1. Thanks to the individually selectable operating medium, completely oil-free, contamination-free and virtually isothermal pumping processes are possible. The double-acting mechanical seal which is employed as standard reliably protects the surrounding environment and the fluid medium itself.

THE RESISTANT CERAMIC SOLUTION
The technical ceramic FRIKORUND® is special developed by us for the pump area. This highly resistant material designed specifically for corrosive media and thus features a previously unattained level of resistance. Combined with different corrosion-resistant materials for the rotating components, the FGP represents one of the most durable and cheapest liquid ring pumps available in the market for corrosive media.

ADVANTAGES:
• Robust - The FGP can accommodate and help to convey up to three times of the required quantity of liquid in multi-phase operation. In order to protect the ceramic components from external influences and any forces, the ceramic is embedded in an armour made from spheroidal graphite cast iron.
• Adaptable - Possible Adaptation for the service liquid to the gas which is to be pumped. The impeller gap can be adjusted from the outside to cater to individual pumping needs.
• Safe - The isothermal compression process prevents overheating of the pumping medium. When the pump is at a standstill, an internal restraint system holds some of the service medium back in the pump. Thus easy starting and stopping of the pump is possible. The pump is protected from running dry and is guaranteed to keep working under any operating conditions. During pump mode, there is no mechanical friction as there is only one moving part in the pump chamber. This ensures a high level of operation.
• Durable - The free-floating impeller and the amply dimensioned shaft and bearing with oil lubrication guarantee an extremely long service life. The sealing by the liquid ring and no moving parts in the pump chamber enable the pump to operate without any wear. Increased rigidity of the shaft ensures a longer useful service life for the shaft seal.
• Easy to Service - The back pull-out design enables the bearing bracket with impeller to be removed without taking apart the casing cover or the connected pipelines. The smart pump design enables a low amount of downtime for servicing.
• Flexible - In addition to speed control, the flow rate can also be adjusted through simple replacement of the impeller and intermediate piece – with fixed installation.
