Welcome to Rinku Engineers, a leading manufacturer and supplier of high-pressure boiler feed solutions. Our advanced range of Boiler Feed and Multistage Feed Pumps is engineered for precision, high thermal stability, and consistent performance under extreme pressure. Designed to meet the critical requirements of steam generation and industrial heating, our pumps ensure a steady, reliable supply of feed water to keep your boilers operating at peak safety and efficiency.
Our Specialized Pump Range
Boiler Feed Pump
The Self Priming Mud Coupled Pump is built for high-torque industrial applications. By coupling the pump to a powerful motor via a flexible drive, these units provide the stability and strength needed for continuous fluid transfer in heavy manufacturing plants.
AMF Multistage Feed Pump
The AMF Multistage Feed Pump is engineered for applications requiring exceptionally high head (pressure). By utilizing several stages of impellers, it builds pressure incrementally, making it the perfect choice for high-rise buildings, industrial pressure boosting, and large-scale boiler systems.
Industries We Serve
Our high-pressure feed pump range is operational across various critical sectors:
-
Power Plants: Reliable feed water supply for steam turbines and heat exchangers.
-
Textile & Processing: Providing consistent pressure for industrial boilers used in dyeing and finishing.
-
Pharmaceuticals: Sterilization and process heating requiring high-pressure steam.
-
Food & Beverage: Boiler systems for pasteurization, cooking, and industrial cleaning.
-
High-Rise Buildings: Efficient water boosting and firefighting systems requiring significant vertical lift.
Solving Your Industrial Pumping Challenges
In high-pressure steam environments, maintaining consistent water levels and managing high-temperature fluids are constant challenges. As a specialized manufacturer and supplier, we address these critical operational issues:
-
Problem: Pressure fluctuations causing inefficient steam generation.
-
Solution: Our AMF Multistage Feed Pump uses multiple impellers in series to generate high pressure with high precision, ensuring a stable and continuous flow into the boiler drum.
-
-
Problem: Rapid seal and bearing failure due to high-temperature feed water.
-
Solution: The Boiler Feed Pump series is constructed with heat-resistant metallurgy and specialized cooling jackets to prevent thermal fatigue and extend the life of internal components.
-
-
Problem: High energy consumption when lifting water to high-pressure boilers.
-
Solution: Advanced hydraulic balancing in our multistage units reduces internal friction, allowing the pump to deliver maximum head with optimized power intake.

Technical Specifications & Features
- Multistage Pressure Building: Successive impellers allow the pump to achieve high discharge pressures that single-stage pumps cannot reach.
- Thermal Integrity: Specifically designed to handle hot water (up to 120°C or more depending on the model) without cavitation or seal leakage.
- Dynamically Balanced Rotors: Ensures vibration-free operation at high speeds, which is critical for the longevity of multistage assemblies.
- Robust Metallurgy: Cast Iron, Stainless Steel, and Alloy Steel options are available to match the chemical and thermal profile of your feed water.
- Easy Maintenance Design: Built with accessible gland packing or mechanical seals to allow for quick inspection and minimal downtime.
Why Choose Rinku Engineers?
At Rinku Engineers, we understand that a boiler system is only as reliable as its feed pump. As a dedicated manufacturer and supplier, every AMF Multistage Feed Pump and Boiler Feed Pump undergoes high-pressure hydrostatic testing and performance curve verification. Our engineering focus ensures that your boiler feed system remains safe, energy-efficient, and capable of meeting high-demand industrial cycles.
Frequently Asked Questions
What is the main difference between a single-stage and a multistage feed pump?
A single-stage pump uses one impeller and is best for low-pressure tasks. A Multistage Feed Pump uses two or more impellers to build pressure gradually, allowing it to move water into high-pressure boilers that a single-stage unit could not overcome.
Can the Boiler Feed Pump handle hot condensate return?
Yes. Our Boiler Feed Pumps are specifically designed to handle hot water. We use specialized materials and seals that remain stable at high temperatures, which is common in steam-recovery systems.
How do I choose the right number of stages for my AMF Multistage Feed Pump?
The number of stages depends on the pressure (head) required to push water into your boiler. Our technical team can help you calculate the exact number of stages based on your boiler’s operating pressure and the piping layout.
Does the pump require a special cooling system?
For very high-temperature applications, we provide pumps with integrated cooling jackets or heat-dissipating fins to protect the bearings and mechanical seals from thermal damage.
