NHCW Series Out-of-Tank Vertical Chemical Pump

The vertical chemical pump—also known as an external vertical submerged pump or a vertical circulation pump for exhaust gas scrubbers—is a type of corrosion-resistant vertical centrifugal pump. The entire unit is mounted on the top exterior of the chemical tank or scrubber tower, with only the suction pipe and pump head extending below the liquid surface to draw fluid, while the motor remains positioned entirely outside and above the tank. Designed as a non-submerged external unit, this non submersible water pump serves as a mainstream chemical pump choice for corrosion-resistant pumping applications across electroplating, exhaust gas treatment, and chemical circulation systems.

Applications & Features

• Wide Medium Compatibility: Serves as a versatile chemical pump suitable for transferring acidic and alkaline liquids, degreasing solutions, PCB chemical fluids, electroplating solutions, as well as water and wastewater treatment.

• Superior Material Construction: The pump body is injection-molded from FRPP or PVDF materials, offering strong resistance to acids, alkalis, and chemical corrosion.

• Operating Temperature: Supports operating temperatures of ≤75°C for FRPP material and ≤90°C for PVDF material.

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

• Dry Running Capability: Supports dry operation without being easily damaged by idled running.

• Slurry Handling: Capable of transferring liquids containing crystalline particles.

• Flexible Installation: Versatile design allows this non submersible water pump to be installed both out-of-tank and in-tank.

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

• Optional Accessories: Suction pipes and coarse filter screens can be added to customize this chemical pump for specific installation requirements.
