CQB series pump is a horizontal, seal less centrifugal magnetic
drive pump, compliant with ISO/ASME/ANSI sealless pump standard for
general emission-free services.
Flow: 7 to 120m3/hr; 31 to 528 GPM
Head: 19 to 52 m; 62 to 170 feet
Temperature: -20 °C to +100 °C ; 68 °F to 212 °F
-Seal-less Teflon lined magnetic drive pump, driven by magnetic
coupling indirectly, motor shaft and pump chamber is completely
sealed, avoid pump leakage problem and use site pollution.
-Wetted part material is PTFE fused with FEP, can transfer low and
high concentration acid, alkali, strong oxidizer etc corrosive
-Robust pump casing. The part contacting with liquid material is
fluoroplastic, pump casing material is cast iron, and pump casing
can bear part of piping and mechanical impact.
-The structure is tightly, safety, and energy-saving.
-Cost-intensive wearing parts are canceled by the seal-less method
of construction, therefore, reduced maintenance costs and long

. Virgin Fluoroplastic
- Considerably easier and more reliable quality control
- No reduction in the permeation resistance.
- Pure pharmaceutical and fine chemical media: no contamination
With ductile cast iron casing absorbs all the hydraulic and
According to DIN/ISO5199/Europump 1979 standard. Comparing to
plastic pumps, no expansion joints are required.Flange with
service-minded through holes to DIN;ANSI,BS;JIS. For flushing
system and monitoring device as required, the draining nozzle will
Spacer sleeve made of Carbon-fiber-reinforced plastic [CFRP]
-The metal-free system does not induce any eddy currents and thus
avoids unnecessary heat generation. Efficiency and operational
reliability benefit from this .Even low flow rates or media near
their boiling point can therefore be conveyed without the
introduction of heat.
Closed impeller with flow-optimized vane channels: for high
efficiency and low NPSH values. The metal core is protected by a
thick-walled seamless plastic lining, the large metal core and
increase the mechanical strength considerably even at elevated
temperature and high flow rates .Secured screw connection to the
shaft to against loosening if the pump is started up in the wrong
direction of rotation or in the case of back-flowing media
