Submersible multistage centrifugal pumps designed for 8-inch wells feature a built-in check valve at the delivery outlet. The pump flange is meticulously crafted to meet NEMA standards, ensuring seamless coupling with motors. These submersible pumps find widespread applications in civil and agricultural settings.
Constructed with precision using stainless steel, all components are manufactured through the advanced lost wax Microfusion technology. The standard material employed is AISI 304 stainless steel, with the option for alternative materials available upon request, including AISI 316 Steel, Duplex steel, and AISI 904L Steel.
To enhance durability and performance, bushing bearings and wear-rings are fabricated from sand abrasion-resistant rubber. Additionally, the reverse-thrust ring is composed of PTFE/Graphite. This comprehensive design ensures reliable and efficient operation in diverse environments.
