Welcome to Rinku Engineers, a premier manufacturer and supplier of specialized heavy-duty pumping equipment. Our specialized range of Vertical Long Shaft Pumps and Solvent Transfer Pumps is engineered for the high-performance handling of volatile, flammable, and hazardous liquids. Designed for “Eva Operation” and deep-tank applications, our pumps provide a safe, leak-proof, and efficient solution for moving industrial solvents from underground storage or deep process vessels.
Our Specialized Pump Range
Vertical Long Shaft Pump
The Vertical Long Shaft Pump is the ideal solution for deep-tank fluid management. By extending the shaft to match your specific tank depth, we ensure that the pump is always primed and ready to operate. These pumps are widely used for transferring clean or contaminated fluids from pits and sumps where horizontal pumps cannot reach.
Solvent Transfer Pump
Specifically built for the chemical and petrochemical sectors, the Solvent Transfer Pump ensures a secure, leak-proof path for hazardous fluids. As a specialized manufacturer, we ensure these pumps are chemically compatible with a wide range of organic solvents, preventing seal degradation and product contamination.
Eva Operation Pump
Specifically engineered for high-precision thermal processes, the Eva Operation Pump is the cornerstone of industrial evaporation and concentration systems. As a specialized manufacturer, we design these pumps to handle the fluctuating pressures and temperatures inherent in Eva operations, ensuring a steady, cavitation-free flow that maintains the integrity of your process cycle.
Industries We Serve
Our vertical and solvent pumping range provides critical support for:
-
Paint & Ink Manufacturing: Safe transfer of solvents, thinners, and chemical binders.
-
Pharmaceuticals: Handling volatile solvents used in extraction and Eva operation processes.
-
Oil & Gas Refineries: Moving fuels, additives, and hazardous chemical waste from deep pits.
-
Chemical Distillation: Circulating fluids through evaporation and recovery units.
-
Agrochemicals: Reliable movement of raw materials and finished solvent-based products.
Precision Engineering for Safe Solvent and Eva Operation
Handling solvents and volatile fluids in deep sumps or tanks requires a pump that eliminates vapor lock and prevents hazardous leaks. As a leading manufacturer and supplier, we address these critical technical challenges:
-
Problem: Risk of fire or explosion when handling volatile solvents with standard pumps.
-
Solution: Our Solvent Transfer Pump is designed with flame-proof motor compatibility and non-sparking components, ensuring the highest level of safety during the transfer of flammable industrial liquids.
-
-
Problem: Inability to lift liquids from deep underground storage tanks.
-
Solution: The Vertical Long Shaft Pump features a customizable extended shaft design that allows the impeller to be submerged deep within the tank while the motor remains safely at the surface, ensuring reliable suction at any depth.
-
-
Problem: Frequent mechanical failures during continuous Eva Operation (Evaporation/Extraction) processes.
-
Solution: Engineered for high-duty cycles, our pumps feature reinforced column pipes and vibration-free shaft assemblies that maintain steady flow rates throughout complex chemical evaporation processes.
-
Technical Specifications & Features
-
Customizable Shaft Length: Engineered to meet the exact depth of your underground tank or process vessel.
-
Glandless or Specialized Sealing: Prevents hazardous solvent vapors from escaping into the environment.
-
Vibration-Free Construction: Precision-aligned bearings and heavy-duty column pipes ensure smooth performance even at maximum lengths.
-
High-Grade Metallurgy: Available in SS-316, SS-304, and specialized alloys to prevent corrosion from aggressive solvents.
-
Back Pull-Out Design: Simplifies maintenance by allowing the rotating assembly to be inspected without removing the entire pump from the tank.

Frequently Asked Questions
What is the maximum depth a Vertical Long Shaft Pump can reach?
As a manufacturer, we can customize the shaft and column length to suit your specific requirements, typically reaching depths from 1 meter to over 5 meters depending on the application and fluid density.
How does a Solvent Transfer Pump handle volatile vapors?
Our Solvent Transfer Pumps utilize specialized vapor-tight construction and high-quality mechanical seals (or glandless designs) to ensure that flammable vapors are contained within the system, preventing atmospheric hazards.
Is the pump suitable for continuous Eva Operation?
Yes. Our pumps are built for continuous duty cycles and are specifically engineered to handle the constant flow and pressure requirements typical of industrial evaporation and extraction processes.
Can these pumps be used with flame-proof motors?
Absolutely. We provide standard mounting configurations that are compatible with all major brands of flame-proof (Explosion Proof) motors to ensure compliance with safety regulations in hazardous zones.
