I. GENERAL
VKDROO Series are the immersion type multisatge centrifugal pump with standard
motor. It adopts the most advanced structure in the world.
Pump head has two types, cast iron type (HT200) and stainless steel tyoe. Other wet
parts are all made of stainless steel (SS304 or SS316) by punching and welding. The
character is low noise, anti-little-corrosion, good appearance, small volume, running
steaadily, easy to install, long service life.

VKDROO Series are used for conveying condensate liquid of machines, lubricating
liquid and conveying condensation water. And they are used for industrial cleaning
equipment or other applications that immersion pump are suitable for.
typical applications:
· Electric spark, lathe, grinding machine, processing center;
· Cooling devices;
· Industrial cleaning equipment;
· Filthering system;
· Farmland irrigation and dehydration;
· Vehicles cleaning, etc.
III. OPERATING CONDITIONS
· Cool, warm, clean, non-fammable, non-explosive liquid without solid grains and
fibers;
· Liquid temperature:
Normal temperature type: -15ºC~+70ºC
Hot water type: -15ºC~+120ºC
· Max. ambient temperature: + 40ºC
· Installation of pump:

V. STRUCTURE
VKDROO Series are vertical multi-stage, segmental type, centrifugal pump. Motor is
directly connected with pump shaft by coupling of pump head. Inlet is at the bottom of
pump and outlet is at the bottom of motor.
Pump operating chamber is composed of suction head, inducer, support diffuser,
diffuser. Ans it is fixed by 4 straps. Rotating part is composed of impellers, shaft
sleeves, circlip cover, mechanical seal, impeller sleeves, nuts which fixed on pump
shaft. Impellers, diffusers are made by new stainless steel stamping and welding
technology. Bearing, mechanical seal is amde by cemented carbides.
Motor rotating directive is counter.clockwise from the motor end.
VI. INSTALLATION
1. The pump should be sited in a well ventilated but frost-free position.
2. The immersion depth should be as deep as possible to prevent from air locks.
3. When installing drainage pipe, do not let the weight of pipe concentrate on the pump
to prevent it from twisting.
4. Motor should be earthed effectively. Electrical device should guarantee pump not be
damage by phase lack, instable power, overload.
5. Install a pressure meter on outlet in order to observe and control pump running.
VII. OPERATION
1. Preparation before start.
1) Check fool bolt if it is loose or not, check cutting ferrule bolt if it is loose or not.
2) It is prohibited to run pump without medium or run pump before venting air. which
will lead to the damage of sliding bearing and mechanical seal.
2. Startup & Circulate.
1) Start motor, check the motor turning, open the outlet valve, adjust it to yhe
required working condition. Suggestion: The flow sholud be kept at the scope of
0.5~1.3 times of the rated flow.
2) Check the fluctuation of manometer and vibration of pump. When assure there is
air in liquid, loose bolts of cutting ferrule in time and vent air.
3) Notice the noises while it’s operating, if there is any abnormal noises stop and
check immediately.
3. Stop.
1) Close valve slowly and close other meters.
2) Switch off the power.
4. Others.
1) Pump should not be started too frequently. Pump shall not be started more than
100 times per hour if the motor power is less or equal to 4 kw, when motor power is
more tah 4 kw, pump shall not be more than 20 times in one hour.
2) According to pump operation and time, check pump, pump pressure, leakage,
motor temperature rising, etc. regurlarly.

VIII. ASSEBLE AND DISASSEMBLE
1. VKDROO 1,2,3,4,8,16,20
1) Put the circlip cover on the shaft.
2) Fit the impeller, impeller sleeve, diffuser, support diffuser, etc. Continue the
assemble order until the last impeller is fitted. Then fit the impeller cover, washer,
screw the nut. Note the position of the support diffuser. For pump with less stages,
the last one is support diffuser. For pump with more stages, support diffuser should
be increased accordingly. The distance of each support diffuser should be even, and
it should fit support sleeve anb bearing.
3) Fit inducer and inlet&outlet chamber.
4) Press stationary part of mechanical seal to pump head.
5) Put the pump head with O ring on the above parts. Screw four straps into suction
head, fasten four nuts of pumps head. Do not tighten one nut completely at one
time, but tighten them symmetrically in turn.
6) Install motor and coupling, screw the bolts in coupling (but not tighly), press the
coupling aand shaft down to the direction of inlet, then lift it about 1mm in reverse
direction, tighten the screws. Note that the space between the two couplings should
be equal.
7) Rotate the coupling to ensure taht the shaft can rotate freely and not be choked.
2. VKDROO 32,42
1) Put the bottom bearing on suction head, fit washer and tighten all the nuts, then fit
inducer.
2) Fit the bottom sleeve and cover on the shaft. Put the first impeller on the shaft,
tighten the nuts and put the impeller on the neck ring base of inducer, then put on
the diffuser, impeller, support diffuser, until the top diffuser.
3) Fit pump head ans straps, tighten the screws.
4) Fit the mechanical seal on the pump head, then fit the seal cover, tghten the
screws, and tighten the screws in the mechanical seal. Lift the shaft and insert the
adjusting slice, the fit coupling.
5) Fit motor which is coupled wth transformer flange to pump head, fasten screws.
6) Fit the coupling, tihten screws, and take out the adjusting slice. Rotate the
coupling to ensure taht the shaft can rotate freely and not be choked and loose.
Reverse the above process to disassemble the pump.
Fault Cause Solution
Motor can’t be started
1. Power supply fails
2. Motor overload
3. Something wrong with circuit
1. Check power supply
2. Check system
3. Check circuit
Pump no water
1. Run reversely
2. Immersion not enough
3. Not enough water in pump, there is
air in suction head or in pump
1. Adjusting motor connection
2. Lower motor installation position
3. Increase water, vent air
Insufficient flow
1. Pipes jammed
2. Neck ring wears out
3. Not correct model
1. Clean pump and pipelines
2. Replace neck ring
3. Re-selct model
Pump coonsumes
too big power
1. Too big flow
2. Motor bearing wears out
1. Make flow smaller
2. Replace motor
Abnormal noise
and pumps no water
1. Water level is too low
2. The temperature of pumped liquid
is too high
1. Check pump suction and liquid level
2. Low pump suction height or
decrease liquid temperature
Too big noise 1. Motor bearing or pump spare parts
broken
1. Replace motor bearing or pumps
