Product Description
The Seal-less Self Priming Pump combines self-priming convenience with magnetic drive or canned motor technology for zero-leakage operation. Its integrated priming chamber handles installations above fluid level, while the seal-less design eliminates fugitive emissions and seal maintenance. The pump handles flow rates from 5 to 500 m³/h at heads to 100 m and temperatures to 150°C, with material options including cast iron, stainless steel, and alloys. Ideal for hazardous, toxic, and expensive fluid transfer in chemical and pharmaceutical plants.
Applications
- Chemical tank unloading
- Railcar loading/unloading
- Marine fuel transfer
- Industrial wastewater
- Underground tank emptying
- Mobile transfer units
Quality Assurance
All Seal-less Self Priming Pumps are manufactured under ISO 9001 quality management system. Each pump undergoes rigorous testing including hydrostatic pressure test, performance test, NDT inspection, and dynamic balance verification before shipment. We provide comprehensive documentation including test reports, material certificates, and operation manuals.
Why Choose Our Self Priming Pumps
Fully Fluoroplastic Construction
All wetted components constructed from solid fluoroplastic (PTFE/PFA), providing maximum corrosion resistance for extreme chemical service.
Self-Priming Capability
Integral priming chamber enables suction lift up to 5m, suitable for chemical drum emptying and above-ground tank transfer.
Extreme Chemical Resistance
Solid fluoroplastic construction handles concentrated acids, strong oxidizers, and halogenated solvents at temperatures up to 120°C.
Lightweight Design
Solid fluoroplastic construction reduces weight compared to metal-lined pumps, simplifying installation and portability.
