OUTLINE

Model IHF pump is a single-stage single-suction fluoric

plastic alloy chemical centrifugal pump, designe d per the

national standard and designed and made per the processing

workmanship for the non-metal pump. This pump features

anti-corrosion, wearability, high temperature resista nce, non-

aging, high mechanical strength, non-toxin decomposition and

wide temperature range of use, with the medium temperature

to be transported at -85 ~ 200 , and is applicable for the

liquid transportation, waste water treatment and souring etc.

technological flows in chemical industry, pharmacy, petroleum,

metallurgy, electric power, electric-plating, acid cleaning, far m

chemicals, paper-making etc. trades. This pump can be used

to transport sulfuric acid, hydrochloric acid, nitric acid, acetic

acid, hydrofluoric acid, nitro-hydrochloric acid, strong oxidative

and strong corrosive media and is one of the most advanced

corrosion-proof equipments at present.

MODEL IHF SINGLE-STAGE SINGLE-SUCTION FLUORINE-PLASTIC ALLOY CHEMICAL CENTRIFUGAL PUMP

CONSTRUCTION AND FEATURE OF PUMP

IHF

(F46)

99.9%

For model IHF fluoric plastic centrifugal pump, the

casing is a metal crust interlined with poly-perfluoroethylene-

propylene (F46), both impeller and pump cover are fo rmed

with a metal insert wrapped with fluoric plastic outside and

then integrally sintered and pressed, the shaft seal is an ext-

ernally mountable sylphon bellows mechanical seal, the static

ring is made of 99.9% alumina ceramic or silicon carbide and

the dynamic ring is made of tetrafluoro filling material or

silicon carbide and its features come at an advanced and rea-

sonable structure, strong corrosion resistance, strict and reliable

sealing, stable work, low noise and a long duration.

PRECAUTIONS AT INSTALLATION

1. It acts an important influence on the normal work of

the pump whether the pump is reasonably mounted, so both

installation and correction must be carefully carried out.

2. Preset the foot bolts and make the concrete basis acc-

ording to the installation dimensions.

3. When the basis cement gets solid, mount the pump

onto it and level both pump and motor with a leveler and, if

unleveled, use sizing blocks to regulate and then tighten the

bolts.

4. Check if the moving parts on the pump are jammed

and collided and check the concentricity between the shafts

of both pump and motor, which can be made correctly by

means of adju sting with a sheet, and finally check the moving

clutch, which shall be lightly movable without collision.

5. Set both suck-in and vomiting pipes with a stand se-

parately and do not le t the pump directly bearing the weight

of the pipelines to prevent it from damage.

6. When the pump is mounted over the liquid level

(within the permitted suction stroke range), mount a foot valve

on the end of the suck-in pi peline and set a liquid-pouring

screwed hole or a valve on the vomiting one for the purpose

of pouring liquid into the pump before start; when the pump

is mounted be low the level, mount a control valve and a filter

on the suck-in pipeline to prevent impurities from being

sucked into the pump, with the filtering area bigger than t he

area of the pipeline by 3-4 times.

7. For the pump of a high head, a check valve shall also

be mounted on t he pipeline at the outside end of the exit flow

control valve so as to prevent the water hammer destruction

at an abrupt stop.

8. The installation height of the pump shall conform the

net positive suction head of it and both pipeline loss and

medium temperature need to be considered.

9. When the pump is used with a suction stroke, mount

a foot valve at the end of the incoming water pipe, do not

leave too many curved conduits with both inlet and outlet

pipelines and make sure of non-water, non-air leaks.

10. It will be better for a filtering screen to be set on the

inlet pipeline so as to prevent im purities from getting into the

impeller and the effective area of the screen shall be 3-4 times

that of the incoming water pipe so as to ensure the liquid to

go through smoothly.

11. For the sake of safety and convenient use and care,

mount a regulating valve on both inlet and outlet pipelines of

the pump unit and a pressure gauge near the pump exit so as

to make it sure for the pump to work within the rated range

and ensure normal work and duration of it.

12. When the inlet needs to be expanded for connection,

use an eccentric reduced pipeline joint.

Start

1. When the pump is used with a suction stroke, that is

the inlet comes as a negative pressure, first pour water into the

pipeline or lead water in with a vacuum pump to have both

pump and inlet pipeline full of water. The inlet pipeline must

be sealed without air leak.

2. Close the gate valve and the cork on the pressure

gauge on the outlet pipeline to reduce the starting current.

3. Turn the rotor several turns to have the bearing lubri-

cated, check if both impeller and seal ring are collided with

each other when moving and, if unmovable, do not start the

pump till finding out the cause.

4. Carry out a trial start, the motor shall be moving in

the direction identical to that the arrow on the pump indicates.

Open the cork on the pressure gauge.

5. When the rotor gets to the normal run and the pressure

gauge shows a pressure, gradually open the exit valve and

adjust it to the desired working condition.

Run

1. When the pump is at running, check the readouts on

the meters and have the pump work with both flow and head

set on the name plate as can as possible, without working with

a big flow.

2. Check the cu rrent value of the motor at a regular time

interval and it shall not be over the rated one.

REPAIR AND MAINTENANCE OF PUMP


3. The bearing temperature shall not be over 75 and

over the outside one by 35 .

4. Loosen the packing gland when the pump starts running

and then set it properly when the expanding graphite or packing

gets expanded completely.

5. Replace the easily wearable parts on time when they

are worn out excessively.

6. In case of an abnormality, stop the pump and check

the cause.

Stop

1. Close the gate valve on the outcoming water pipeline

and put on the cork on the vacuum meter.

2. Stop the motor and then close the cork on the pressure

gauge.

3. In winter or a cold season, drain out the liquid inside

of the pump to prevent it from frozen crack.

4. In case of a long time stop, disassemble the pump,

clean and lubricate it and then keep it properly.

1. Check both pump and motor and replace the easily

wearable parts periodically.

2. Often lubricate the bearing box with quality calcium

based lubri cating grease to have it in a good lubricated status.

3. In case of a long time stop, in addition to getting the

corrosive liquid inside of the pump drained out completely,

much attention shall be paid to the cleaning of the part s and

the runner therein and cut-off of the power.

4. Never have the pump idly running.

5. Set a filter at the entrance of the pump if there are

solid grains in the medium.
