Product Introduction

1、 Overview
The WFB series unsealed self-priming pump is the first product to fill the domestic gap. This product has multiple functions such as temperature and pressure resistance, "one-time drainage", and "lifelong self-priming". At present, we produce a series of complete machines made of various materials such as 321, 304, 316, 316L, A3, PP (reinforced polypropylene), etc., with five different shapes and more than one thousand specifications. Widely applicable in industries such as electronics, power, chemical, metallurgical, pharmaceutical, food, electroplating, environmental protection, fire protection, municipal, water purification, national defense and military, textile printing and dyeing, mining and mineral processing, and civil construction, it has received high praise from users.

Unique advantages
1. Our company adopts the "pump series multi-faceted centrifugal sealing device", which eliminates the traditional filling seal, packing seal, and mechanical seal of water pumps, completely eliminating the "running, emitting, dripping, and leaking", and is the most ideal equipment to replace various long shaft submersible pumps, submersible pumps, and so on.

2. The sealing device does not rub or wear during operation, and its service life is more than 10 times longer than similar products.

3. The principle of transplanting vacuum pump has stable and reliable self-priming performance, especially with the use of an "electric air control valve", which truly achieves "one-time drainage, lifelong self-priming".

4. Low vibration, low noise, flexible movement, easy disassembly and installation, no need for foot fixation.

5. It has superior self-control function and can be used in conjunction with high-tech fields and highly automated systems.

The characteristics of different shapes for different purposes
Rectangular and conical shapes provide you with different installation options; Explosion proof type suitable for flammable and explosive environments; Outdoor type, with the help of a safe three-dimensional household cover, effectively prevents rain, fog, moisture, and dampness when working outdoors; The trolley mobile type can move the water pump to any workstation you need for operation.

2、 Explanation on the power of the supporting motor
In order to reasonably match the motor, we draw on the advanced experience of developed countries and divide the water pump into three working condition adaptation levels: A, B, and C. The motor power matched in this manual is based on the A-level level. If you use it in Class B and C working conditions, you can reduce the power of the supporting motor according to the specific situation.

The A-level operating conditions are: continuous operation, suction, flow, and head all meet the specified standards for the selected model;

The B-level operating conditions are: continuous operation, only two of the three performance requirements need to be met;

The C-level operating conditions are: interval operation, with only one of the three performance requirements meeting the standard;

3、 Selection method
(1) The meanings of 1-5 in the "Category Code" column of the performance parameter table are: Type 1 is rectangular, Type 2 is conical, Type 3 is explosion-proof, Type 4 is outdoor, and Type 5 is cart mobile. The four letters G, PP, and BXG in the "Material Symbol" column represent four materials: steel, reinforced polypropylene, and stainless steel (1Cr18Ni9Ti).

(2) Example of Model Meaning:

50WFB-AD1

50- Pump inlet diameter (mm)

WFB - Non sealed Self controlled Self priming Pump

AD1- Performance Classification

(3) Complete model writing method. Assuming that the requirements for the water pump are: the shape is a trolley mobile type, the material is reinforced polypropylene, the suction diameter is 50mm, and the performance classification is AD1. The complete model of this water pump is "5PP50WFB-AD1"

Assuming the shape of the water pump is rectangular explosion-proof, other requirements are the same as above. The complete model of this water pump should be written as "1.3PP50WFB-AD1"

Assuming the design of the water pump is conical explosion-proof, with other requirements as above, the complete model of this water pump should be written as "2.4PP50WFB-AD1"
