1. Our factory 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 an ideal equipment to replace various long shaft submersible pumps, submersible pumps, submersible sewage 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, easy installation, and 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 usage characteristics of different shapes:
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 during outdoor operations; The trolley mobile type can move the water pump to any workstation you need for operation. 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 A, B, and C working condition adaptation levels. 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, and all three performance indicators of suction, flow, and head must meet the standards specified by the selected model;
The B-level operating conditions are: continuous operation, with only two of the three performance criteria meeting the standards;
The C-level operating conditions are: interval operation, with only one of the three performance requirements meeting the standard; selection method The meaning of "1-5" in the "Category Code" column of the performance parameter table is: Type 1 is rectangular, Type 2 is conical, Type 3 is explosion-proof, Type 4 is outdoor, and Type 5 is cart mobile. In the "Material Symbol" column, T G. The four letters PP and BXG respectively represent four materials: iron, steel, reinforced polypropylene, and stainless steel (1Cr18Ni9Ti).
(2) Example of Model Meaning:
65WFB-A 65- represents the inlet diameter of the pump (mm)
WFB - stands for unsealed self controlled self-priming pump
A - represents 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 40mm, and the performance classification is AD1. The complete model of this water pump is "5PP40WFB-AD1".
Assuming that the water pump has a rectangular explosion-proof design and other requirements are the same as above, the complete model of this water pump should be written as "1 • 3PP40WFB-AD1".
Assuming the design of the water pump is a conical outdoor type, with the same requirements as above, the complete model of this water pump should be written as "2 • 4PP40WFB-AD1".
(4) The flanges of our water pumps are manufactured according to the national standards of the People's Republic of China. Standard code GB9115.2-88; GB9115.3-88 。 The flange pressure of non-metallic material water pump is 0.6MPa; The flange pressure of the metal material water pump is 1.0MPa. When our water pump leaves the factory, each inlet and outlet is equipped with a counter flange.
