Overview

IHFD Fluoroplastic Centrifugal Pump

Product Details

1、 Introduction to IHFD Fluoroplastic Centrifugal Pump

The IHFD corrosion-resistant fluoroplastic centrifugal pump body adopts a metal shell lined with F46 (or imported PFA high-temperature fluoroplastic), and the pump cover, impeller, and shaft sleeve are all made of metal inserts wrapped in fluoroplastic and sintered as a whole. The shaft seal adopts an advanced external corrugated pipe mechanical seal, and the inlet and outlet are reinforced with cast steel bodies to enhance the pressure resistance of the pump.

This type of pump has the advantages of corrosion resistance, wear resistance, high temperature resistance, anti-aging, high mechanical strength, smooth operation, advanced and reasonable structure, strict and reliable sealing performance, easy disassembly and maintenance, and long service life.

2、 Technical parameters of IHFD fluoroplastic centrifugal pump

3、 Characteristics and Applications of IHFD Fluoroplastic Centrifugal Pump

1. The curved part of the pipeline should be as smooth as possible, reducing the use of bends and avoiding placing bends near them.

4. Considering the descent of the liquid level, the position of the suction pipe should have sufficient submergence depth. To prevent the installation of filters at the inlet, the filtering area should be greater than 3-4 times the cross-sectional area of the pipeline. And fixed

5. Pump suction. When used under working conditions, the inlet pipe of the pump must be equipped with a valve, which can be used to adjust the specified flow point to prevent motor overload and pump failure after exceeding the flow rate.

6. Install pipeline compensators at the inlet and outlet of the pump as much as possible to facilitate maintenance.

7. The pipeline must be connected correctly, and the sealing gasket between the flanges must be flat and not misaligned. If the pump fails to function properly, it may cause damage to the pump.

4、 Installation of IHFD Fluoroplastic Centrifugal Pump

（1） Installation points

1. The pump should be installed and fixed on a stable foundation, unaffected by other mechanical vibrations.

2. The weight of the foundation itself must be more than three times the mechanical weight, and the area must be larger than the base.

3. Adequate space should be reserved around the pump for maintenance and repair.

4. Place the pump unit on the foundation, and a cushion should be laid between the base and the foundation.

（2） Pipeline

1. The inlet and outlet pipelines of the pump should have brackets and cannot be supported by the pump. The diameter of the pipeline should be consistent with that of the pump. The pump should be located as close as possible to the water tank.

2. It is necessary to ensure that the installation height of the pump meets the cavitation allowance of the pump, and to consider pipeline losses and medium temperature. To avoid gas cavitation in the pump body, the following equation must be met:

NPSHa≥NPSHr+0. 5

NPSHa， Effective (device) cavitation allowance (m) NPSHr: required (pump) cavitation allowance (m)

10°

(Pa Pv) NPSHa=---- soil hs hf

Pa: pressure acting on the surface of the conveying medium (MPa) Pv: vapor pressure of the medium (MPm)

g: Gravitational acceleration (m/s)

p: Medium density (kg/m3)

Hs: suction height (m)

HF: suction pipe resistance (m)

5、 IHFD Fluoroplastic Centrifugal Pump Safety Precautions

1. Prohibited from air transportation: Air transportation can cause the impeller to heat up and the mechanical seal to be damaged by dry friction, resulting in pump damage. (Running with the import and export valves closed is also considered as air freight operation).

2. Preventing static electricity damage: When transporting liquids with low conductivity, such as ultra pure water or fluorine-containing inert liquids, static electricity will be generated in the pump, which can cause discharge and damage to the pump. Measures should be taken to prevent static electricity generation, divert static electricity, or take other measures.

3. Pump maintenance personnel should have professional knowledge and operational experience.

4. Centrifugal pumps made of specific materials can only be used for specific working conditions, otherwise, the normal performance and service life of the pump cannot be guaranteed, and accidents may even occur.

5. Ventilation requirements on site: When transporting media that are prone to volatile toxic gases, safety measures must be taken, such as installing ventilation equipment, to prevent liquid leakage in case of sudden accidents.

6. Preventing liquid leakage: Preventive measures must be taken for liquid leakage caused by emergencies or pipeline damage to avoid direct liquid flow into the ground.

7. Select electromagnetic switches based on the specifications of the motor, such as rated voltage and rated power.

8. If the pump is outdoors, protective measures must be taken for the electrical circuit to prevent water from entering the switch.

9. Electromagnetic switches and button switches should be installed safely and kept away from the pump.
