ZW series self-priming sewage pump application scope:
Compared with similar domestic products, the ZW type self-priming sewage pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, and easy use and maintenance. It belongs to the domestic * series of sewage pump products. All technical performance indicators rank domestically and have reached the international advanced level, with broad application markets and development prospects. 1. Environmental temperature ≤ 45 ℃, medium temperature ≤ 60 ℃. 2. The pH value of the medium is 6-9 for cast iron pumps and 1-14 for stainless steel pumps. 3. The maximum diameter of the particles is 60% of the pump diameter, and the fiber length is 5 times the diameter. 4. The total weight of impurities in the medium shall not exceed 15% of the total weight of the medium, and the specific gravity of the medium shall not exceed 1240 kg/cubic meter.
Compared with similar domestic products, the ZW series self-priming sewage pump has the characteristics of simple structure, good self-priming performance (self-priming height can reach 5m), strong sewage discharge capacity, high efficiency and energy saving, and easy maintenance (can completely replace WQ and QW submersible sewage pumps). It is among the top domestic sewage pump series products. All technical indicators are at the domestic level and have reached the international advanced level. Has broad prospects for application market development.
ZW self-priming non clogging sewage pump integrates self-priming and non clogging sewage discharge, adopts a hybrid axial reflux, and passes through the pump body The unique design of the impeller flow channel allows for the suction and discharge of large solid particles and long fiber impurities without the need for a bottom valve or inlet water like a typical self-priming water pump. Widely used in municipal sewage engineering, river pond manure treatment, sedimentation of waste minerals and impurities, as well as impurity pumps for chemical media such as light industry, papermaking, food, chemical industry, pharmaceuticals, electricity, paddles and mixtures.

Advantages and installation knowledge of self-priming sewage pumps:
1. Strong overcurrent capability: The special impeller anti blocking design ensures high efficiency and no blockage of the pump;
2. Efficient and energy-saving: Adopting excellent hydraulic models, the efficiency is 3-5% higher than that of general self-priming pumps;
3. Good self-priming performance: The self-priming height is 1 meter higher than that of a typical self-priming pump, and the self-priming time is shorter than that of a regular self-priming pump.
Installation and usage knowledge
1. Before installing the self-priming sewage pump, check if the foundation is level;
2. Check whether each component has been damaged during transportation;
3. The self-priming sewage pump itself is not allowed to be used as a pipeline support;
4. The self-priming sewage pump and pipeline should maintain good sealing. Check if the fasteners at the connection parts such as the pump base, coupling, and bearings are loose? If there is looseness, it should be tightened;
5. Check for any jamming or abnormal noise when manually rotating the coupling;
6. Open the water inlet valve above the pump, add no less than two-thirds of the pump body volume of stored liquid water, and close the valve. No need to refill water when starting up in the future;
7. Connect the power and try turning it on. From the motor end, it turns clockwise. (Reverse is strictly prohibited);
8. Turn on the device and observe if it runs normally? If there are any abnormal phenomena, the cause should be identified and eliminated.
