Maxima-C - Model DV0301C-CL -Large Capacity Liquid Ring Vacuum Pumps

SHARE

The Maxima-C is a robust design, which features conical porting instead of flat plate porting offered on the Maxima-KTM. The cones are attached to the end housing of the pump and protrude into the impeller on both sides. Air enters the impeller in a radial direction versus axially when compared to the flat plate design.

The primary benefit of this design is its ability to handle more seal liquid or liquid carryover through the suction compared to the flat plate design with less effect on power consumption and better performance when handling saturated inlet gas. The Maxima-C features a shrouded rotor and heavy-duty cones and bearings. Packed gland sealing is standard with optional mechanical seals available. Other features include removable bearing brackets, multiple inlet/discharge port configurations and a casing partition allowing for different operating pressures at each inlet port. The Maxima-C pumps are available in capacities ranging from 700 to 22,000 ACFM, multiple material configurations and are manufactured to ISO 9001:2015 quality standards. Bolt in replacements are available for the NASHTM CLTM series, 904TM series and ATTM series. Selection of Maxima-C versus Maxima-K depends on operating conditions and the most efficient operating point.
