1、 The unique detachable structure enables it to have the following detachable functions:
1. The motor and some detachable functions of AYSLB double suction pump: The motor used in the detachable pump has a high degree of universality. If it is necessary to replace the same model of motor or water pump, simply disassemble and remove the clamp type coupling, and then remove the connecting screws between the motor and the bracket to remove the motor or water pump for replacement.
2. The mechanical seal replacement function of AYSLB double suction pump is easy to remove: When replacing the mechanical seal of the easy to remove pump, there is no need to remove the motor, just open and remove the clamp type coupling, and then open the seal cover to remove the mechanical seal for replacement.
2、 Compact structure and beautiful appearance: This series of pumps is a detachable structure that integrates the machine and pump, with a beautiful appearance. Its vertical structure determines a small installation area, which not only reduces the pump room area, improves the area and space, but also greatly saves infrastructure investment. If IP54 outdoor motors are used, it can save more investment in pump room infrastructure.
3、 Easy installation: The specifications of the pump inlet and outlet flanges are designed to be the same as those of standard valve flanges, and are located on the same centerline with a low center, making it convenient for pipeline layout. The pump room design is also more reasonable and practical.
4、 Absolute easy disassembly function, convenient maintenance, and low maintenance cost:
1. The AYSLB double suction pump adopts a sealed detachable structure. When repairing mechanical seals, there is no need to disassemble the motor and inlet and outlet pipelines. Only the clamp type coupling needs to be disassembled and removed, and then the sealing cover on the pump cover needs to be disassembled and removed to replace the mechanical seal. Maintenance is very convenient and labor-saving.
5、 Stable and Long Service Life: The AYSLB double suction pump adopts a specially designed clamp type coupling, which has smooth operation, low noise, high component concentricity, and increases the smoothness of operation, resulting in a long service life.
6、 High efficiency and good performance: The impeller adopts a new double suction structure hydraulic model design and manufacturing, eliminating the shortcomings of the original vertical pump with large radial tension. The impeller is always in a suspended state during operation, with high efficiency and good performance. At the same time, it also reduces the flat wear of graphite bearings, thereby improving the service life of the water pump and reducing operating costs.
7、 Innovative design, unique structure, and cost savings in operation and management: adopting a brand new internally placed water lubricated bearing, utilizing high-pressure return fluid from the water pump outlet to enter the pump base through the return pipe for self lubrication, without the need for lubricating oil, thus not polluting the conveying medium and eliminating the trouble of regular oil injection. We use imported graphite impregnated resin bearings with nickel based alloy shaft sleeves and thrust discs, which have the characteristics of high wear resistance, low friction coefficient, anti-aging, and anti silt. In addition, the bearings are equipped with thrust discs that can withstand the self weight thrust of the pump impeller.
8、 Reliable and leak free sealing: The shaft seal adopts high-quality machinery, and the sealing friction pair uses graphite to silicon carbide or silicon carbide to hard alloy, which is wear-resistant, leak free, and has a long service life.
9、 Standardization, serialization, and high universality of components: For example, if the motor adopts Y or Y2 series B5 type, it belongs to the standard universal motor, which is easy and fast to maintain and upkeep.
10、 This series of detachable vertical single-stage double suction pumps belongs to the new generation of detachable vertical pumps developed by our company. Compared with other detachable pumps, it has unique advantages: the total height of the SLB type double suction pump is greatly reduced without affecting the function of disassembling the seal. Because only the mechanical seal is disassembled, the connection bracket between the pump and the motor is particularly short, and the stability is stronger. Moreover, when replacing the mechanical seal of the sealed detachable pump, no matter how high the power of the water pump is, even if there is only one maintenance worker on site, as long as he can handle the half piece coupling, he can independently complete the maintenance work of the seal, achieving the absolute function of disassembling and repairing.

product overview

The AYSLB detachable vertical single-stage double suction centrifugal pump is the latest domestic vertical double suction pump specially designed by our company for urban water supply, heating, air conditioning and refrigeration industries according to market demand. This series of products is widely used in water plants, pump stations, air conditioning circulating water, heating hot water circulation, industrial water supply systems, fire protection systems, shipbuilding industry, and is also suitable for general use in the oil refining industry.
This vertical pump is a bold breakthrough design in the overall structure, with a water lubricated bearing structure built into the pump base, solving the problems of the original detachable pump bracket being too high, the detachable parts being too heavy, requiring too many maintenance personnel, and incomplete disassembly; The impeller and pump body are designed and manufactured using a new type of double suction hydraulic model, which eliminates the shortcomings of the original vertical pump with large radial tension. During operation, the impeller is always in a suspended state, with stable performance, long service life, and high efficiency. The motor adopts Y or Y2 series standard universal motors, which have the characteristics of matching and easy replacement, solving the problem of difficult replacement of the original vertical pump extension shaft motor matching; At the same time, the disassembly structure of the AYSLB double suction pump solves the problem of difficult mechanical seal replacement for the water pump.
This series of products has irreplaceable advantages such as balanced operation, long service life, more convenient matching, and easier maintenance. It is the most ideal product to replace conventional centrifugal pumps such as ISG, IS centrifugal pumps, S-type double suction pumps, and other types of detachable pumps.
