Features

• Standard modularization design.

Thanks to the rear pull-out design, it's possible to remove the bearing pedestal, impeller, and shaft seal without having to move the volute casing. This convenient feature saves time and effort in the maintenance process.

The seal chamber of ISO 21049/AP1682 can accommodate various types of seals, with the shaft being sealed by a cartridge mechanical seal along with API flushing plans.

The casings with a diameter of DN 80 (3") and above feature a double volute on the discharge branch. Can you please provide text that closely resembles this information?

• Efficient air fins cooled bearing housings.

This type of roller bearing is designed to handle high radial loads with ease. To balance out the axial loads, back-to-back angular contact bearings are used. This configuration ensures optimal performance and longevity for the bearing.

The ZAO open impeller is specifically designed to maximize hydraulic efficiency in slurry applications. It features an adjustable bearing carrier that makes it simple to adjust impeller clearance for optimal performance. With its unique design and high-quality construction, this impeller is an excellent choice for any application that requires reliable, high-performance slurry handling. So if you're looking for a powerful and efficient impeller that can handle even the toughest slurry applications, look no further than the ZAO open impeller.

Suction and discharge flanges with a pressure rating of PN 2.5MPa are established as the standard in GB9113.1-2000. However, it is important to note that the user might require adherence to additional standards.

When observing from the drive end, the pump rotation is in a clockwise direction.

To simplify the alignment configuration process, jack screws (located on the motor side) are available.

There are two options available for lubricating and cooling bearings: oil mist and fan cooling. Oil mist and fan cooling are popular methods used to ensure proper lubrication and temperature control for bearings. These options offer effective ways to extend the lifespan and performance of bearings in various applications. By using oil mist, a fine mist of lubricating oil is directed towards the bearings, ensuring that they are properly lubricated at all times. This method not only reduces friction and wear but also helps to dissipate heat generated during operation. On the other hand, fan cooling involves the use of fans or blowers to provide a continuous flow of cool air to the bearings. This helps in dissipating heat and maintaining the optimal operating temperature for the bearings. Both methods have their advantages and suitability depending on the specific application and operating conditions. It is essential to carefully consider the requirements of the bearing system and select the most appropriate lubrication and cooling method to ensure optimal performance and longevity of the bearings.
