idling-capable vertical chemical pump

Vertical, corrosion-resistant chemical pump engineered for continuous duty in coating, electroplating and exhaust/tower chemical handling applications. Designed for corrosive acids and alkalis, this idling-capable vertical pump minimizes downtime and protects motor bearings from aggressive vapors.

Key features

• Idling-capable design: can operate at low/no flow conditions without damage to the pump (suitable for intermittent/variable process conditions).
• Corrosion-resistant construction: wetted parts are molded from FRPP, CFRPP or PVDF (material selection depends on the delivered chemical) for long life in aggressive chemistries.
• Sealing and vapor protection: shaft seal geometry and a vent on the support plate prevent chemical gas ingress to the motor bearing and allow safe discharge of free vapors.
• Closed impeller: non-directional installation simplifies assembly and maintenance.
• Shaft protection: pump shaft fitted with a protective cover to reduce wear and contamination risk.
• Heavy-duty bearings: reinforced bearing assembly resists axial and radial loads from vertical installation and process upsets.
• Anti-corrosion finish: double-layer anti-corrosion spraying for added external protection.

Common applications

• Exhaust/tower circulation for plating and surface treatment lines
• Acid/alkali transfer in etching and chemical processing
• Outside-tank vertical pumping and sump circulation
• Any industrial process requiring corrosion-resistant vertical centrifugal pumping

Options & ordering notes

• Specify wetted-material (FRPP or PVDF) based on the chemical compatibility and operating temperature
• Confirm duty point (flow, head, fluid temperature and concentration) to select motor power and exact model configuration

This pump is offered as a corrosion-resistant vertical centrifugal solution for engineering-plastic construction requirements in electroplating, coating and other chemical process industries.
