DRC series ANSI Chemical Process Pumps
Performance Curve
Flows to 4540 m3/h (20000 gpm)
Heads to 215 m (700 ft)
Pressures to 27 bar (400 psi)
Temperatures from -75°C (-100°F) to 370°C (700°F)
•Lower total cost of ownership from reverse vane impeller, which eases maintenance and provides renewable, high-efficiency performance over the pumps' life
•Increased reliability and mechanical seal life due to the ideal seal environment created by the SealSentry seal chamber
•Ease of maintenance resulting from optimal, predictable seal chamber pressures that are re-established after every impeller setting
•Extended mechanical seal and bearing life through robust shaft and bearing designs that also minimize shaft deflection
•ASME B73.1 Specification for Horizontal End Suction Centrifugal Pumps for Chemical Process
Flow Modifier Designs
FML (shown above)-Designed with a large gland bolt and gasket circle, the FML is preferred for most applications:
•Single internal cartridge seals
•Dual internalexternal cartridge seals
•Single internal component seals with flexibly mounted seats
•Dual internal"true" tandem design cartridge seals
Cylindrical Bore Designs
CBL (shown above)-With an oversized cylindrical step bore, the CBl is ideal for seals with large gland bolt and gasket circles. It may be used with:
•Dual internal component seals that isolate the seal chamber from the process with external barrier fluid
•Single seal with throttle bushing and flush to boost pressure over flash point
FMS- Similar to the FMl the fms accommodates seals with small gland bolt and gasket circles. It is ideal for all mounting configurations of single seals
CBS- The CBS is designed for packing arrangements and conventional seals with small gland bolt and gasket circles.
FMI-The FMI incorporates a cast-in integral gland. It utilizes the shaft sleeve for seal setting and fast instal-lation. It may be used with Single internal, flexibly mounted seals Sanitary-type applications
