ApplicationsIt is a renewal decided to substitute for Model IH
chemical centrifugal pump and Model F proof corrosion
centrifugal pump. It is applicable to delivering the liquid
which the corrosiveness and adhesiveness is similar to
water in the fields of chemical industry , petroleum ,
metallurgy , generating electricity paper making , food ,
pharmacy ,synthetic-fibre and so on.

StructureCompact vertical single-stage chemical industry pump. It is easy that dismount the pump when the motorpower more than 7.5kW
GB4216.5, Rp1/4 Rp3/8
Casing It has pipe joined spiral casing and uses the best hydraulic model. Suction and discharge nozzles are in one
line with the same diameter. Flange accords with the standard of GB4216.5 and has Rp1/4 or Rp3/8 pressure
gauge.

AdvantagePump unit:
Pump shaft and motor shaft perfectly individual design, convenient to teardown
design , make user very easy to maintain and reduce the cost.
Pump shaft and motor shaft directly rigidity connection , advanced machine
tooled craftwork make the two shaft entirely concentric , reduce the vibration and
reduce the noise.
KQHThe KQHSERIES
The outlet and inlet are same in diameter and the diameters are in the same
line ,Liquid flows smoothly with less loss.
Removal of base plate, Just like valves, the pump can be mounted wherever
on the pipe line.
the most key point,save cost except convenient for replacing pump-sheft
Unique in stallation reduces the occupation of pump, which saves the invest
cost by 40% to 60%.
Perfect design makes sure of no leakage, long life, which saves operation cost
by 50% to 70%.
Adopt the high-quality stainless steel cast, which results in high accuracy in
dimension and nice-looking appearance.

Installation KQH-Pump is specially designed to install the pump directly with the pipe. If the
pump will not bear any pressure in any condition, the gravity of the pump itself and
the center of the pump allow all series of pumps to be installed with pipe directly.
Besides this, baseplate can also be used to support. During installation, except the
direction with the heads of the pump and the motor downward id not allowed, any
other direction are permitted.
For motor of power above 7.5 kW, we suggest to use pulley in installation.

Notes on Order-placing: 1. Name, temperature, density, concentration, treacliness should be clearly noted in the contract l, so that the manufacturer
can make a proper choice of material and power of motor.
2. It should be clearly noted in the contract when special requirement, for instance, capacity, head, inlet pressure, motor
voltage, freq uency, blast-proof etc, are made.
