ZWZ horizontal axial flow pump

ZWZ horizontal axial flow pump is a type of centrifugal pump that is widely used in various industries. In this article, we will discuss its classification and features.

Classification

ZWZ horizontal axial flow pump can be classified according to its capacity, head, and motor power. The capacity of the pump can range from 10m3/h to 5000m3/h. The head can range from 1m to 15m. The motor power can range from 1.1kW to 800kW.

Features

High flow rate

ZWZ horizontal axial flow pump has a high flow rate compared to other types of centrifugal pumps. This makes it suitable for applications where a large volume of liquid needs to be transported.

Low head

ZWZ horizontal axial flow pump has a low head, which means it is not suitable for applications where high pressure is required.

Energy efficient

ZWZ horizontal axial flow pump is designed to be energy efficient. It has a high hydraulic efficiency and low power consumption, which makes it ideal for applications where energy savings are a priority.

Simple structure

ZWZ horizontal axial flow pump has a simple structure, which makes it easy to install, operate, and maintain. It also reduces the risk of mechanical failure.

Corrosion-resistant

ZWZ horizontal axial flow pump is made of materials that are corrosion-resistant, which makes it suitable for applications where the liquid being transported is corrosive.

Low noise

ZWZ horizontal axial flow pump operates at a low noise level, which makes it suitable for applications where noise pollution is a concern.

In conclusion, ZWZ horizontal axial flow pump is a type of centrifugal pump that is suitable for applications where a large volume of liquid needs to be transported. It has a high flow rate, low head, is energy-efficient, has a simple structure, is corrosion-resistant, and operates at a low noise level.

Features

The impeller is high hydraulic efficiency type and is designed to be applicable to the requirements of evaporation system, it is able to adapt the fluctuation of evaporator loading,therefore reduces the energy consumption and increases the output.
Adopting the adjustable impeller to fit different applications.
Butt welding and thermal compensation reduces the investment cost.
Low pump speed and low linear velocity reduces the damage of crystals.
Pipe hung arrangement solved the stress compensation caused by heat expansion, no need of pump baseplate and expansion joint.
Slight vibration,low noise,smooth operation,high efficiency and energy-saving.

Structure

Elbow structure for pump body,piece-welded body and casted body for selection.
Pump impeller is cantilever type with spherical hub,impeller blades are adjustable.
Pump shaft adopts butt welding workmanship,the wetted parts or possible wetted parts are made from stainless steel or other corrosive materials.
Mechanical seal and packing seal can be interchangeable.
Adopting cartridge mechanical seal,reliable and easy for maintenance.
Enlarged cylinder type bearing housing with oil level glass and oil filler,which extends the bearing life and interval of lubricant changing.
Pump and be driven by motor through V-belts,gear box or directly through couplings. For pipe hung pump,the universal joint transmission must be adopted if the motor ≥200kW.
