Perfomance Test : Meral Metal Covered Carbon Bush VS Conventional Gunmetal Bush and Standard Carbon Bush

At Meral Powder Metallurgy Pvt. Ltd., our component performance is validated through comparative testing under real operating conditions in working submersible pump systems. A controlled performance evaluation conducted on a 12.5 HP, 12-stage pump demonstrates the measurable advantages of the Meral Metal Covered Carbon Bush over both conventional Gunmetal Bush and standard market Carbon Bush alternatives.

The test results confirmed higher discharge performance (+1.9 LPM compared to Gunmetal Bush and +1.3 LPM compared to standard Carbon Bush), improved overall efficiency (up to +1.01%), and reduced current consumption (up to −0.154 Amp), while maintaining stable head performance within normal operating tolerance.

These improvements indicate reduced internal friction losses, better dimensional stability during operation, and improved hydraulic efficiency inside the pump assembly. The results clearly establish that Meral Metal Covered Carbon Bush delivers enhanced energy efficiency, smoother shaft support, and more reliable long-term operating performance compared to conventional bush materials.

Perfomance Test : Meral Metal Covered Carbon Bush VS Conventional Gunmetal Bush

At Meral Powder Metallurgy Pvt. Ltd., our commitment to quality is validated through real pump performance testing under controlled operating conditions. A comparative test conducted on a 10 HP, 20-stage submersible pump clearly demonstrates the measurable advantages of the Meral Metal Covered Carbon Bush over a conventional Gunmetal Bush.

The testing results confirmed higher discharge (+0.13 LPS), improved overall pump efficiency (+3.97%), reduced current consumption (−0.08 Amp), and increased developed head (+7.14 meters). These improvements indicate lower internal friction, better sealing performance, and reduced wear clearance during operation.

The results prove that Meral Metal Covered Carbon Bush enhances hydraulic performance while reducing energy consumption and mechanical losses, making it a more efficient and reliable solution for high-performance submersible pump applications.

Field Perfomance validation - Pumps Running With Meral Carbon Bush

Meral Carbon Bushes are actively operating inside field-installed submersible pump systems across multiple configurations and working environments. The following field performance videos demonstrate strong and consistent water discharge from pumps operating with Meral Carbon Bush under real working conditions, including operation in muddy water environments.

These installations highlight the ability of Meral Carbon Bush to support reliable pump performance where stable flow output and operating consistency are essential. The observed discharge behavior reflects the effective running characteristics and operational suitability of Meral bushes inside working submersible pump assemblies.

In addition to controlled performance comparisons with conventional Gunmetal Bush and standard market Carbon Bush alternatives, these real-world installation results provide practical validation of the efficiency and reliability delivered by Meral Carbon Bush in demanding field applications. The successful operation across multiple pump setups confirms their suitability for long-term service performance and dependable operation in actual installation conditions.
