Introduction
The S series pumps are single-stage, double-suction, horizontal split-case pumps designed for high-volume water transfer across a wide range of applications. These pumps are available in 43 different sizes, ranging from 80mm to 400mm discharge, and can handle flow rates up to 4000 cubic meters per hour with head capacities reaching up to 160 meters. The design allows for easy maintenance, as all major wear components and replaceable parts are easily accessible without the need for special tools or removing the suction and discharge piping.
Key Features
* Designed with a horizontal, vertical axis medium open-type double pump shell structure, featuring lining made of cemented carbide or rubber for excellent wear resistance, corrosion resistance, and high reliability.
* High-efficiency hard alloy material and low NPSH (Net Positive Suction Head) for improved performance.
* A brief type structure for bearing parts is used, with high load capacity design and alloy bearing grease lubrication to ensure smooth operation under various conditions.
* Adjustable clearance between the protection board and impeller ensures optimal pump efficiency.
* Offers multiple sealing options such as packing seal, impeller seal, and container-type mechanical seal to suit different operating requirements.
* Pump and drive can be connected via straight-line transmission, triangular, hydraulic transmission device, or reducer drive.
* The outflow direction can be installed at eight different angles to adapt to diverse site installation conditions.
* Available in multiple series to meet long-distance transmission needs.
