Vertical Seal less Pump
Introduction :
The Vertical Sealless Pump is designed for demanding industrial applications where leakage, corrosion, and maintenance downtime are not acceptable. Built with advanced corrosion-resistant materials and a true sealless structure, this pump delivers safe, reliable, and maintenance-free fluid handling, even in harsh chemical environments.
The Vertical Seal-less Pump from HIS Pumps and Systems is a corrosion-resistant, direct-driven vertical centrifugal pump designed for reliable, leak-free recirculation of corrosive and particle-bearing liquids. It delivers up to 1,000 LPM and 35 m head while requiring no bearings or lubrication.
Salient Features :
✅ Seal-less Design – eliminates mechanical seal wear and common leakage points
✅ Corrosion-Resistant Body – GFR-PP / CFR-PP construction for long life in aggressive chemistries
✅ Dry-Running Capable – safe operation without liquid film; reduces downtime risk
✅ Particle Handling – engineered to pass solids and suspended matter
✅ Low Maintenance – no bearings, no lubrication, no coupling means fewer service points
✅ Built-in Leakage & Gas Protections – partial cut seals for stop leakage and dry seal for gas handling
✅ Compact & Direct-Driven – no bypass line and no pump-motor coupling for simplified installation

What is a vertical sealless pump? A vertical sealless pump is a pump that operates without mechanical seals, preventing leakage and reducing maintenance, especially for corrosive or hazardous liquids.
Can a seal-less pump run dry? Yes — the Vertical Seal-less Pump is designed to run dry without damage, reducing risk during transient conditions.
What chemicals can GFR-PP and CFR-PP handle? Glass-fiber and carbon-fiber reinforced polypropylene are selected for resistance to a wide range of acids, alkalis and plating chemistries; confirm compatibility with your specific fluid.
Does this pump require lubrication or bearings? No. It operates without bearings or lubrication, ensuring minimal maintenance.
Is coupling required between pump and motor? No — this pump is direct-driven and does not require a coupling, simplifying installation and alignment.
Can this pump handle suspended solids? Yes — it is engineered to pass and pump liquids containing particles and suspended matter.
