ZCQ corrosion-resistant self-priming magnetic pump-Global supplier

North of Linpu Street, Dongou Industrial Zone, Dongou Street, Yongjia County, Wenzhou City, Zhejiang Province

Product Overview:

ZCQ type self-priming magnetic pump (hereinafter referred to as self-priming pump) is a new product that has been developed based on the requirements of many users, incorporating new foreign technologies on the basis of CQ type magnetic pump, and successfully researched and tested by our engineering and technical personnel. Its performance has reached the advanced level of similar foreign products in the 1990s. The ZCQ magnetic pump replaces dynamic seals with static seals, ensuring that the overcurrent components of the pump are in a completely sealed state, completely solving the problems of running, emitting, dripping, and leaking that cannot be avoided by other pump mechanical seals. The materials of the pump body and overcurrent components are made of corrosion-resistant stainless steel, steel jade ceramics, PTFE stone and other materials, which not only have the function of CQ type magnetic drive pump, but also integrate self-priming, without the need for bottom valves and drainage water, and self-priming height of 4 meters.

main features

The ZCQ self-priming magnetic pump has a compact structure, beautiful appearance, small volume, low noise, reliable operation, and easy maintenance. It can be widely used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, scientific research and other units to pump acids, alkalis, oils, rare and valuable liquids, venoms, volatile liquids, as well as circulating water equipment, especially for the pumping of easily leaking, flammable and explosive liquids. Therefore, it has a wide range of uses, and we sincerely recommend this product to users.

Installation and use:

1. After opening the box, check the pump nameplate and verify whether the main parameters of the self-priming pump product are consistent with the usage requirements.

2. Self priming pumps should be installed horizontally, and the pump body should not bear the weight of the pipeline.
3. The pump and pipeline should maintain good sealing.
4. Before using the pump, it should be checked that the motor fan blades rotate flexibly, without stopping or abnormal noise, and that all fasteners are firm.
5. Unscrew the water adding bolt above the pump, add less than two-thirds of the pump body volume of the stored liquid, and tighten the bolt.
6. Connect the power supply and try to turn it on. From the motor end, check if the operation is consistent with the pump direction mark.
7. Before the pump stops working, close the discharge valve first, then turn off the power, and finally close the suction pipe valve.

Precautions for use:

1. Due to the fact that the cooling and lubrication of magnetic pump bearings rely on the medium being transported, it is absolutely forbidden to operate them in idle mode, while also avoiding the possibility of spatiotemporal rotation caused by power outages and restarts during operation.
2. If the conveyed medium contains solid particles, a filter screen should be added to the pump inlet; if it contains ferromagnetic particles, a magnetic filter should be added.
3. The ambient temperature of the pump during use should be less than 40 ℃, and the temperature rise of the motor should not exceed 75 ℃.
4. The conveyed medium and its temperature should be within the allowable range of the pump material (see attached table for details). The operating temperature of the metal pump is ＜ 100 ℃, and the specific gravity of the conveyed medium is ≤ 1.3; When the specific gravity of the medium is less than 1.3, it will affect the technical performance.

5. For media that are prone to precipitation and crystallization during transportation, they should be cleaned promptly after use to drain the accumulated liquid in the pump.
6. After 500 hours of operation of the self-priming pump, the wear of the bearings and end face dynamic rings should be inspected. If the gap between the bearings and the shaft sleeve is greater than 0.5-1mm and the impeller moves 0.5-2mm in the axial direction, the bearings and axial dynamic rings should be replaced.

Reason for malfunction and solution:

failure mode	cause	Troubleshooting
Self suction magnetic pump does not produce water	a、 Reverse rotation of water pump	Change the motor wiring
	b、 Air leakage in the inlet pipeline	Eliminate air leakage
	c、 Insufficient water storage in the pump chamber	Increase storage capacity
	d、 The voltage is too high, causing the coupling to slip during startup	Adjust the positive voltage
	e、 The suction distance is too high	Lower the installation position of sand
	f、 The valve is not open	Correct or modify the valve
Insufficient flow rate of self-priming magnetic pump	a、 The suction pipe diameter is too small or clogged	Replace the inlet pipe
	b、 Impeller channel blockage	Clean the impeller
	c、 Head too high	Turn up the outlet valve
	d、 Insufficient rotational speed	Restore rated speed
The head of the self-priming magnetic pump is too low	a、 Excessive traffic	Turn down the outlet valve
The head of the self-priming magnetic pump is too low	b、 The speed is too low	Restore rated speed
The noise of the self-priming magnetic pump is too loud	a、 Severe wear of the shaft	Replace the pump shaft
	b、 Severe wear of the shaft sleeve	Replace the shaft sleeve
	c、 Drive the magnetic steel cup to contact the isolation sleeve	Dismantle the pump head and reassemble it
	d、 Grinding of sealing ring and impeller	Replace the thrust ring and sealing ring
Self suction magnetic pump leakage	O-ring damaged	Replace the O-ring seal
