NHCN Series Vertical In-Tank Chemical Pump

The in-tank pump—also known as a vertical immersion pump or in-tank vertical pump—is a specialized vertical centrifugal pump where the pump head is directly immersed below the liquid level of the tank or vessel, while the electric motor remains positioned above outside the tank. Specifically engineered for in-tank fluid circulation, chemical transfer, and fluid lifting, these high-durability chemical resistant pumps feature zero shaft seal leakage risk, reliable dry-running capability, and exceptional acid-and-alkali resistance. When transferring harsh media, this heavy-duty acid pump delivers safe, leak-free operation across aggressive chemical chemical processing environments.

Applications & Features

• Wide Medium Compatibility: As versatile chemical resistant pumps, they are suitable for transferring acidic and alkaline liquids, degreasing solutions, PCB chemical fluids, electroplating solutions, and handling water or wastewater treatment operations.

• Superior Material Construction: The pump casing and wetted components are precision injection-molded from FRPP or PVDF materials, offering strong resistance to aggressive chemical attack when operating as an acid pump.

• Operating Temperature: Supports fluid operating temperatures up to 75°C for FRPP material and up to 90°C for PVDF material.

• Dry Shaft Seal Design: Features a dry shaft seal structure to prevent corrosive acid gas from entering and damaging motor bearings during vertical centrifugal pumpoperation.

• Dry Running Capability: Built with dynamic dry-running performance, ensuring the pump is not easily damaged by idling or dry operation.

• Slurry Handling: Capable of transferring challenging chemical liquids containing crystalline particles and solid impurities.

• Flexible Installation: Highly versatile mounting options allow this vertical centrifugal pump to be installed directly in-tank or mounted out-of-tank.

• Vapor Seal Gasket: Equipped with a specialized vapor/acid mist seal gasket to safeguard motor bearing operation and protect the surrounding workspace.

• Optional Accessories: Suction pipes and coarse filter screens can be added to customize these chemical resistant pumps for specific operational requirements.
