Product Overview VMC vertical barrel multistage pump is structure of multistage, radial-split. The impeller is single suction type with sectional type diffuser and single shell. The first stage impeller is suction type which can improve pump the capacity of cavitation resistance.
The outer shell of pump endures the inlet pressure and the length of shell or the pump installation depth depends on the requirement of NPSHA.
The shaft seal adopts the single mechanical seal or serial chemical seal with the cooling, flushing or sealing liquid systems.
The pump rotation is clockwise viewing from drive end.
Performance Range Flow : up to 800m3/h (3,520 gpm) Head :up to 800m (2,625 ft) Design Pressure : 10.0Mpa (1450 Psi) Operating Temperature : -180~ +150 ℃ Outlet diameter: DN40-200mm
Structural Features Low suction velocity can design First stage impeller with low NPSHr Axial thrust balancing device with balance drum ISO 21049/API 682 seal chamber accommodates multiple seal types Flanged spacer coupling Inside drain line Heavy-duty thrust bearings with axial adjustment above baseplate level Oil lubricated thrust ball bearings Sleeve bearings are lubricated by pumped liquid Casing and impeller wear rings Optional inducer
Applications It can transport clean or contaminated, low or high temperature, neutral or corrosive media. ■Refinery ■ Petrochemical plant ■ Cryogenic engineering ■ Pipeline boosting ■ Offshore platform ■ Power station ■ Condensate drainage
