HET Engineering & Pumps Industries Pvt. Ltd. has officially launched the HDEW Series, a two-stage high head dewatering pump built for industries where standard pumps simply cannot keep up.

What Is the HDEW Series?

HET Engineering & Pumps Industries Pvt. Ltd., based in Ahmedabad, Gujarat, has proudly announced the launch of its latest product (HDEW Series). This is a two-stage submersible pump designed specifically to tackle ultra-high head dewatering challenges in demanding industrial environments.

Whether it is a deep mining pit, a thermal power plant, or a large construction site, the HDEW Series is built to handle high head application, the kind of heavy workload where ordinary pumps fail to perform at high head conditions.

Who Is This Pump For?

The HDEW Series is not a general-purpose pump. It is built for industries and project sites that deal with extreme conditions, deep water levels, and non-stop operational demands.

• Mining Operations Handles deep pit dewatering where water needs to be pumped out from significant depths without interruption.
  
• Thermal Power Plants Manages raw water transfer and cooling water systems that run around the clock.
  
• Hydropower Stations Supports intake and dewatering operations in hydro projects where water pressure and head are consistently high.
  
• Large Infrastructure Projects Keeps construction sites and tunnelling operations free from water accumulation during critical project phases.
  
• Industrial Dewatering Applications Clears standing water from industrial facilities, processing plants, and heavy-duty work sites efficiently.

If your site demands a pump that works hard, runs long, and does not break down under pressure, the HDEW Series is the right fit for the job.

Why Choose the HDEW Series?

When a project runs in tough conditions, the pump you choose can make or break your operations. The HDEW Series brings together performance, durability, and efficiency in one package built for real industrial demands.

• Ultra High Head Performance The HDEW Series can pump water up to 200 meters of head, making it one of the most capable pumps in its class for deep dewatering and high-lift raw water transfer.
  
• Two-Stage Heavy Duty Hydraulic System The pump uses a robust 2-stage impeller and diffuser system with hydrodynamically balanced impellers. This design ensures stable performance even under continuous heavy-duty operation.
  
• Low Energy Consumption Despite its power, the HDEW Series is engineered for high efficiency and low running cost, so your operations stay productive without excessive power bills.
  
• Designed for Tough Site Conditions It works in both vertical and horizontal installations, handles corrosive and abrasive liquids, and is built with materials that resist wear over long periods of use.

These four strengths together make the HDEW Series a pump you can rely on shift after shift. It is not just about moving water, it is about keeping your project on schedule without unexpected downtime.

Technical Specifications of the HDEW Series

A pump is only as good as the engineering behind it. Here is a detailed look at the hydraulic design and motor specifications that make the HDEW Series perform reliably in the most demanding conditions.

Advanced Two-Stage Hydraulic Design

The hydraulic system of the HDEW Series is what sets it apart from single-stage pumps. Every component is engineered to deliver maximum output with minimum stress on the machine.

• Robust 2-Stage Impeller and Diffuser System: A dual-stage setup that generates significantly higher head than conventional single-stage pumps, ideal for deep and high-lift applications.

• Hydrodynamically Balanced Impellers: Balanced impellers reduce vibration and mechanical wear, ensuring smoother operation and a longer pump life.

• Designed for High Efficiency and Low Running Cost: The hydraulic path is optimised to move more water using less energy, keeping your electricity costs under control over long operational hours.

• Suitable for Vertical and Horizontal Installation: Gives you the flexibility to install the pump in the orientation that best fits your site layout and project requirement.

• Suitable for Corrosive and Abrasive Liquids: The hydraulic components are built to withstand contact with chemically aggressive or particle-heavy water without premature degradation.

Electrical and Motor Specifications

The motor powering the HDEW Series is selected for reliability, power range flexibility, and compatibility with standard industrial electrical setups.

• Available Models:  2PHDEW4-50 / 2PHDEW6-100 / 2PHDEW6-120 — three model options to match different flow and head requirements.
  
• Power Supply: 415V / 3 Phase / 50 Hz, with 60 Hz variants also available for international project sites.
  
• Rated Power: 37 kW to 90 kW, covering a wide range of project scales from mid-size dewatering to large industrial operations.
  
• Maximum Submergence Depth: 15 to 25 meters, suitable for most dewatering and raw water intake scenarios.
  
• Thermal Protection: Available as an optional feature to safeguard the motor against overheating during extended or high-load operation.
  
• Single Electrode Leakage Detection Sensor: Detects moisture ingress early, alerting operators before it can cause damage to the motor or electrical components.

These specifications reflect a pump that is engineered with both performance and longevity in mind. Whether you are running it at a mining site or infrastructure project, the HDEW Series is built to keep up without compromise.

Materials and Construction of the HDEW Series

The performance of a pump depends just as much on what it is made of as how it is designed. Every material used in the HDEW Series is chosen to handle harsh environments, resist wear, and deliver a long and reliable service life.

• Motor Body: High Strength iron material grade provides a strong and rigid outer body that can withstand mechanical stress, impact, and the physical demands of heavy industrial sites.
• Shaft (Stainless Steel): The stainless steel shaft offers excellent strength and corrosion resistance, ensuring the rotating core of the pump stays stable and intact even in aggressive liquid conditions.
• Mechanical Seal (Silicon Carbide / Tungsten Carbide): These are among the hardest sealing materials available. They handle high pressure, abrasive particles, and corrosive liquids without breaking down, keeping the pump leak-free over extended use.
• Rubber Parts (Nitrile / Viton): Both Nitrile and Viton are industrial-grade rubber compounds known for their resistance to oils, chemicals, and extreme temperatures, making them the right choice for demanding pump environments.
• Wetted Parts: Manufactured from high-strength material grades such as Cast Iron / Stainless Steel / Ni-Hard / Hi-Chrome to ensure durability, hydraulic stability, and resistance to wear in demanding applications.

NOTE: Also these pump are available as per customer require material of construction like S.S. 304 /S.S.316/NI HARD/ HI CHROME or any other, We also provided if any specific part with special material of construction as per application

Maximum Corrosion Resistance and Long Service Life: Every material in the HDEW Series works together to fight corrosion from the inside out. This means fewer replacements, lower maintenance costs, and a pump that stays operational longer on every project site.

When you invest in the HDEW Series, you are not just buying a pump. You are putting a machine on your site that is built to outlast tough conditions and keep performing without frequent servicing or part replacements.
