Installation Methods:

The two primary installation methods are:


lCoupled Installation: By using a coupler, the pump seamlessly connects to the pipeline. Maintenance is easy, as the pump can be lifted from the discharge pipeline effortlessly. We provide couplers suitable for different pump sizes.


lPortable Installation: Connect the pump's outlet directly to temporary piping or a hose. The pump can either be positioned at the base or suspended. This method is apt for smaller pumps and temporary setups.


Our Services:

lTechnical Support & Installation Drawings: Comprehensive technical assistance is available, and customized installation drawings can be provided based on your requirements.


l18-month Warranty: We believe in our product's durability, hence provide an 18-month warranty for peace of mind.


lMaintenance & Spare Parts: Our dedicated team is available for repairs, and we maintain a stock of spare parts for replacements when needed.


lCustomized Installation Components: Installation accessories, including guide rails and bases, can be customized to your specifications, eliminating the need for additional external purchases.


lControl Cabinets: You have options for control cabinets made from carbon steel or stainless steel. Multiple start-up methods are also available, such as soft start, variable frequency, and autotransformer start.



How does the variable speed control enhance energy efficiency?

The ability to adjust the pump's operational speed based on requirements ensures it runs at optimum efficiency, thus consuming only the necessary energy.
