Welcome to Rinku Engineers, a premier manufacturer and supplier of high-pressure positive displacement pumping solutions. Our specialized range of Plunger Pumps and Piston Plunger Pumps is engineered for applications requiring extreme pressure and precise flow control. Designed to handle everything from clean water to aggressive chemicals and viscous fluids, our pumps are built for heavy-duty industrial performance and long-term mechanical durability.
Our Specialized Pump Range
Plunger Pump
The Plunger Pump is the go-to solution for high-pressure industrial tasks. By moving a cylindrical plunger through a high-pressure seal, it generates immense force. These pumps are ideal for hydro-testing, high-pressure cleaning, and water jetting applications where durability is non-negotiable.
Piston Plunger Pumps
Our Piston Plunger Pumps offer versatile performance for chemical metering and process industries. As a specialized manufacturer, we ensure these units are engineered with precision-ground components to handle aggressive fluids and high-viscosity liquids with consistent efficiency and safety.
Industries We Serve
Our plunger and piston range provides reliable high-pressure movement for:
-
Oil & Gas: Chemical injection, well-head maintenance, and hydrostatic testing.
-
Chemical & Pharma: Precise metering and injection of aggressive or sensitive fluids.
-
Food Processing: High-pressure homogenization and industrial cleaning systems.
-
Construction & Mining: High-pressure jetting for surface preparation and de-scaling.
-
Reverse Osmosis (RO): Providing the necessary high pressure for industrial desalination and water purification.
Precision Engineering for Extreme Pressure Applications
In industrial cleaning, chemical injection, and high-pressure processing, maintaining a constant flow at varying pressures is a critical challenge. As a leading manufacturer and supplier, we address these demanding operational needs:
-
Problem: Inconsistent flow rates when working against high back-pressure.
-
Solution: Our Plunger Pump utilizes a positive displacement design, ensuring a fixed volume of liquid is moved with every stroke, providing unmatched flow accuracy regardless of the system pressure.
-
-
Problem: Rapid wear of internal components during high-pressure cycles.
-
Solution: The Piston Plunger Pumps are built with high-grade ceramic or hardened stainless steel plungers and robust valve assemblies, significantly extending the life of the pump in 24/7 industrial environments.
-
-
Problem: High maintenance costs and complex seal replacements.
-
Solution: Our pumps feature a streamlined liquid-end design that allows for quick access to seals and valves, reducing downtime and simplifying routine servicing.
-

Frequently Asked Questions
What is the difference between a Plunger Pump and a Centrifugal Pump?
A Plunger Pump is a positive displacement pump that moves a fixed volume of water with every stroke, making it ideal for very high pressure. A centrifugal pump uses a spinning impeller and is better for high volume but lower pressure.
Can Piston Plunger Pumps handle corrosive chemicals?
Yes. As a manufacturer, we offer Piston Plunger Pumps with specialized chemical-resistant manifolds and plungers (like Ceramic or Hastelloy) specifically designed for the safe injection of aggressive chemicals.
Does a Plunger Pump require a relief valve?
Yes. Because it is a positive displacement pump, it will continue to build pressure if the discharge is blocked. We always recommend installing a high-quality pressure relief valve (PRV) for system safety.
How often do the seals need to be replaced?
Seal life depends on the fluid and pressure. However, our high-pressure Plunger Pumps are designed with premium packing sets that offer extended life and are easy to replace during scheduled maintenance.
