Welcome to Rinku Engineers, a premier manufacturer and supplier of specialized pumping systems for aggressive chemicals. Our range of Sulphuric Acid Transfer Pumps is specifically engineered to handle the extreme challenges of transporting concentrated and dilute acids. Built with superior corrosion-resistant materials and leak-proof technology, our pumps ensure the highest levels of safety and operational efficiency in chemical processing environments.

Our Specialized Pump Range

Sulphuric Acid Transfer Pump
The Sulphuric Acid Transfer Pump is the industry standard for bulk unloading, tank-to-tank transfer, and process dosing. Designed to handle the unique “exothermic” nature of the acid, these pumps maintain hydraulic stability even as fluid temperatures fluctuate during the transfer process.
Industries We Serve
Our specialized acid pump range provides reliable support for:
-
Fertilizer Manufacturing: Handling phosphoric and sulphuric acids for nutrient production.
-
Chemical Refineries: Safe transfer of acids used in catalysis and intermediate synthesis.
-
Metal Pickling & Steel: Circulating acidic baths for surface treatment and scale removal.
-
Pharmaceuticals: Precise dosing of acids for pH control and chemical reactions.
-
Dyes & Pigments: Managing corrosive raw materials in high-volume production cycles.
Engineering Safety for Concentrated Acid Handling
Handling Sulphuric Acid requires precise material selection to prevent rapid equipment failure and hazardous leaks. As a leading manufacturer and supplier, we address these critical safety and technical challenges:
-
Problem: Rapid corrosion and heat generation when handling varying concentrations of acid.
-
Solution: Our Sulphuric Acid Transfer Pump is available in specialized metallurgies like Alloy 20, Hastelloy, and high-grade Stainless Steel, as well as non-metallic linings like PVDF, ensuring total structural integrity against chemical attack.
-
-
Problem: Hazardous fumes and liquid leakage endangering workforce safety.
-
Solution: We offer advanced sealing options, including double mechanical seals with external flushes or completely sealless magnetic drive designs, to ensure 100% containment of hazardous fluids.
-
-
Problem: Frequent maintenance due to the high specific gravity and viscosity of concentrated acid.
-
Solution: Every pump is built with heavy-duty bearings and reinforced shafts to manage the high mechanical loads associated with dense chemicals, reducing downtime and extending service life.
-
Technical Specifications & Features
-
Advanced Metallurgy Options: Available in Alloy 20, SS-316L, and specialized plastics to match acid concentration and temperature.
-
Heavy-Duty Casing Design: Thick-walled construction provides an extra safety margin against erosion and internal pressure.
-
Sealless & Magnetic Drive Capability: Optional technology that eliminates the mechanical seal entirely for zero-leakage peace of mind.
-
High Specific Gravity Compatibility: Optimized motors and impellers designed to move heavy, dense fluids efficiently.
-
Back Pull-Out Construction: Simplifies maintenance by allowing the rotating assembly to be serviced without disconnecting the acid pipelines.
Why Choose Rinku Engineers?
At Rinku Engineers, we prioritize the containment of hazardous materials. As a dedicated manufacturer and supplier, every Sulphuric Acid Transfer Pump undergoes rigorous pressure testing and material verification to ensure absolute reliability. We provide customized configurations tailored to your specific acid concentration—whether 98% concentrated or highly dilute—ensuring your plant remains safe, compliant, and productive.
Frequently Asked Questions
What is the best material for a 98% Sulphuric Acid Transfer Pump?
For highly concentrated acid at ambient temperatures, we often recommend Alloy 20 or high-grade Stainless Steel. For higher temperatures or varying concentrations, PVDF-lined or Hastelloy pumps provide superior protection.
Can these pumps handle Sulphuric Acid with impurities or solids?
Yes. For “dirty” acid applications, we offer semi-open impellers and abrasion-resistant internal components that prevent clogging and premature wear from suspended solids.
Why is a sealless pump recommended for acid transfer?
A sealless or magnetic drive pump removes the risk of seal failure—the most common cause of acid leaks. This protects your employees, prevents environmental damage, and reduces the need for expensive seal cooling systems.
How do I select the right motor for high-concentration acid?
Sulphuric acid has a high specific gravity (up to 1.84). As a manufacturer, we pair our pumps with high-torque, energy-efficient motors that can handle the increased weight of the fluid without overloading.
