ZA type stainless steel corrosion-resistant petrochemical pump

Description :

ZA type stainless steel petrochemical pump is a single-stage single suction cantilever centrifugal pump, mainly used for conveying clean or particle containing liquids, low or high temperature liquids in industrial sectors such as petroleum, chemical, synthetic fiber, fertilizer, power station, metallurgy, food and medicine. The conveying medium temperature is generally -70 ℃~180 ℃. Performance characteristics: The ZA stainless steel petrochemical pump is a single-stage, horizontal radial volute pump with a foot support for the pump body. Single suction radial impeller, axial suction, radial discharge. According to the usage conditions, use front and rear wear rings and balance holes for hydraulic balance. The packing box has cooling and heating pipe joints. The energy-saving technical parameters of this series of pumps have stable operating performance, which can ensure the stability of the conveying medium and the consistency of the flow rate. Its structural science. ZA petrochemical pumps adopt optimized design and manufacturing processes, with compact structure, small volume, small footprint, and easy installation and maintenance. Suitable for various working conditions, such as clean or media containing solid particles, low or high temperatures, neutral or corrosive media, gas-liquid two-phase flow, etc. Its material has strong corrosion resistance, and its components are made of stainless steel, high-strength cast iron, copper and other materials, which can withstand the erosion of various strong corrosive media. It is also suitable for flammable and explosive gas and liquid environments, reducing safety hazards and risks. The ZA type petrochemical pump has high flow and pressure regulation capabilities, meeting different process requirements. Capable of providing head and flow range to meet different conveying requirements. Low noise and vibration. Reduce adverse effects on the work environment and equipment, improve workplace comfort and equipment stability. The impeller is the core component of the pump, and its streamlined design can effectively improve the efficiency of the pump. The shaft is a component that connects the pump body and impeller, and its material is generally made of high-strength stainless steel. Sealing is one of the key components of a pump, and its performance directly affects the service life and performance of the pump. The shaft seal adopts packing seal, and can also use single end face seal and double end face mechanical seal. Balanced mechanical seals can also be used. And equipped with cooling, flushing or sealing systems. The flow range of this pump is 1.6~2600m3/h, and the head is 5~300m. Procurement Notice: The ZA series petrochemical process pump has a single-stage single suction cantilever rear opening structure, so there is no need to disassemble the suction and discharge pipelines when repairing the pump. After disassembling the pump cover, the suspension and rotor components can be extracted from the pump body, making maintenance work very convenient. There is a sealing ring on the rear cover plate of the impeller, which can basically balance the axial force, and the residual unbalanced force is borne by the thrust bearing. The bearing is a ball bearing lubricated with oil, and the oil ring lifts the oil and can automatically control the oil level. When the working temperature is below 250 ℃, the suspension does not need to be cooled. When the working temperature is above 250 ℃~450 ℃, the suspension is air-cooled or water-cooled. According to different situations, some pumps have a double volute structure, while others have a single volute structure. The shaft seal can be sealed with packing or with a single or double end mechanical seal, and is equipped with a cooling, flushing, or sealing fluid system. Directly driven by an electric motor, connected to the motor through a coupling.
