Welcome to Rinku Engineers, a premier manufacturer and supplier of high-performance vertical pumping solutions. Our specialized range of Vertical Sump Pumps and Polypropylene (PP) Vertical Sump Pumps is engineered for efficient fluid transfer from pits, tanks, and sumps. Designed to handle everything from clean water to highly corrosive chemical waste, our pumps offer a glandless design that ensures leak-proof performance and maximum operational safety.
Our Specialized Pump Range
Vertical Sump Pump
The Vertical Sump Pump is the standard for industrial dewatering and fluid transfer from pits. Available in various metallurgies, these pumps are suspended into the liquid, allowing the motor to remain safely above the sump. They are ideal for transferring clean water, cooling tower water, and industrial runoff.
PP Vertical Sump Pump (Polypropylene)
Specifically built for the chemical processing industry, the PP Vertical Sump Pump offers superior resistance to aggressive fluids. As a specialized manufacturer, we ensure these pumps are thermally stable and capable of handling corrosive effluents where metallic pumps would typically fail.
Industries We Serve
Our vertical sump range provides reliable fluid movement for:
-
Chemical & Pharma: Safe transfer of corrosive raw materials and waste from underground tanks.
-
Effluent Treatment (ETP): Lifting industrial waste and sludge from collection pits for treatment.
-
Textile & Dyes: Managing color-laden effluents and acidic wash water.
-
Electroplating: Circulating and transferring chemical baths in plating shops.
-
Steel & Pickling: Handling acidic waste and hazardous pickling fluids.
Solving Your Industrial Pumping Challenges
In complex industrial setups, maintaining system pressure and ensuring the longevity of mechanical seals are critical challenges. As a premier manufacturer and supplier, we provide advanced engineering solutions for these operational needs:
-
Problem: Limited floor space for high-pressure water boosting.
-
Solution: Our Vertical Multistage Pumps feature a stacked impeller design that generates immense pressure while occupying only a fraction of the floor space required by horizontal units.
-
-
Problem: Frequent mechanical seal failure in harsh pumping conditions.
-
Solution: Our Multi Spring Accessories provide even pressure distribution across the seal face, accommodating shaft misalignment and reducing wear for a longer service life.
-
-
Problem: Reduced pump performance due to worn or inefficient rotating parts.
-
Solution: We manufacture high-precision Centrifugal Pump Impellers dynamically balanced to restore hydraulic efficiency and reduce vibration in your existing pump systems.
-
Technical Specifications & Features

Frequently Asked Questions
What is the main advantage of a Vertical Sump Pump over a submersible pump?
While both work in pits, a Vertical Sump Pump keeps the motor above the liquid level, making it easier to maintain and protecting the electrical components from the fluid, especially when handling corrosive chemicals.
Can the PP Vertical Sump Pump handle high temperatures?
Our PP Vertical Sump Pumps are designed to handle temperatures up to 70°C–80°C. For higher temperature requirements, we offer specialized material grades or PVDF options to ensure structural integrity.
Does a Vertical Sump Pump require priming?
No. Because the pump impeller is submerged in the liquid within the sump, these pumps are naturally primed and ready for immediate operation.
How do I determine the right length for my sump pump?
The length depends on the depth of your tank or pit. Our technical team works with you to manufacture a customized column length that ensures the suction remains near the bottom for maximum drainage.
