Frequently Asked Question about
Hungerät Water Pumps

Hungerät solar pumps come with a 1-year warranty from the date of manufacture. Extended warranty options can be discussed for larger projects.

Yes, our pump is built for tough environments. It performs well in temperatures as low as -40℃ and as high as 60℃, based on lab testing.

To estimate the number of solar panels, multiply your pump’s rated power by 1.3 (or 1.5 for high-power models), then divide by the wattage of a single panel.

Wattage is just part of the equation — you also need to check that the total voltage fits within the controller’s input range (VOC and MPPT).

Not sure how to calculate it? Feel free to send us your pump model and panel specifications —- we’ll help you figure it out quickly.

We don’t recommend using it in seawater or heavily sandy water, as this reduces lifespan. For special water sources, contact us for suitable solutions.

Options include brass, stainless steel, and cast iron, depending on your budget and application. Stainless steel is the most durable for long-term use.

No. Most solar pumps are plug-and-play. We provide clear manuals and can guide you through setup.

Make sure the pump is filled with water (primed) and the suction pipe is airtight. Also check if the water source is blocked. If the issue continues, inspect the impeller and seals for wear or damage.

Signs include unusual noise, reduced flow rate, or visible leaks around the pump. If water pressure drops significantly despite normal operation, it may be time to replace the impeller or seal. Hungerät provides spare parts and guidance to make maintenance simple.

Yes, we offer 1 year warranty for surface pumps, covering manufacturing defects and performance issues.

Always install the pump with a foot valve or check valve to keep water in the suction pipe. For added protection, you can use a dry-run protection switch or a pressure control device to automatically shut off the pump when water is unavailable.

Yes, it is highly recommended. A foot valve or check valve prevents water from flowing back into the source, helps maintain prime, and ensures smooth operation of your surface pump.

Place it on a stable surface, connect the suction pipe with a foot valve, fill the pump with water, and connect the outlet. Follow the manual for best performance.

It’s designed to lift clean water from deep wells, boreholes, or reservoirs, typically used for household supply, irrigation, and small-scale industrial applications.

Depending on the model, Hungerät deep well pumps can lift water from 20 meters up to 300+ meters. Always check the rated head before purchase.

Key factors are well depth, water yield, pipe diameter, and daily water demand. Share these details with us and we’ll recommend the best-fit model.

We recommend only for clean or slightly sandy water. Heavy sand or muddy water can damage the impeller and shorten lifespan.

The pump is lowered into the well with a safety rope, connected to the discharge pipe and power cable. We provide manuals and can guide you step by step.

Yes, all Hungerät AC deep well pumps come with a 1-year warranty against manufacturing defects.

We supply replacement parts like impellers, seals, and motors, plus 24/7 technical support to keep your pump running smoothly.

It’s designed for clean or slightly dirty water, perfect for irrigation, household water supply, small ponds, and light construction drainage.

Most QDX pumps operate safely at 5–7 meters submersion depth, depending on the model. Always check specifications before use.

Most QDX pumps use 220V single-phase household power. Larger versions may require 380V three-phase.

Always keep the pump fully submerged. A float switch or water level controller is strongly recommended to avoid dry running.

Rinse and clean the pump after use, check the seal, impeller, and bearings regularly, and store it dry if unused for a long period.

Hungerät provides a 1-year warranty for QDX pumps against manufacturing defects.

Spare parts like seals, impellers, and bearings are available directly from Hungerät or our authorized distributors.

A regular sewage pump is designed for wastewater with small particles. Cutter pumps come with built-in blades that can cut fiber, rags, or solid waste, preventing clogging in harsher environments.

Most sewage pumps come in 220V single-phase for households and 380V three-phase for industrial or heavy-duty applications.

Choose the right model for your environment, install the pump with a proper base or screen, and schedule regular cleaning. Cutter pumps are especially effective against clogging caused by fibers or rags.

No. Sewage pumps must remain submerged during operation. Using a float switch or level controller is strongly recommended to prevent dry running.

Yes. Hungerät offers impellers, seals, bearings, and motor parts, along with technical support and guidance worldwide.

All Hungerät sewage pumps come with a 1-year warranty against manufacturing defects.

In-line pumps are widely used in water circulation, HVAC systems, cooling towers, and water supply for buildings. They are designed for continuous, stable operation.

The pump is mounted directly on the pipeline, which makes installation easy and space-saving. Always ensure the pump shaft is horizontal and that the inlet and outlet are aligned.

Yes. Depending on the model, Hungerät in-line pumps can handle cold, hot, or slightly corrosive water. Please confirm temperature limits when selecting.

Small and medium in-line pumps can usually be installed directly on the pipe without a foundation. Larger models may require additional support to reduce vibration.

They are generally quiet, especially compared to traditional centrifugal pumps. Proper installation and alignment will further minimize vibration and noise.

Regularly check seals, bearings, and motor temperature. Ensure the pump is not running dry and that the pipeline is clean to prevent blockages.

Yes. All in-line pumps include a 1-year warranty, and we supply seals, impellers, and other spare parts for maintenance.

No. The intelligent controller automatically detects pipe pressure and calculates the optimal starting pressure for your system.

Yes. The electronic pressure sensor works in any orientation — installation is flexible and easy.

Yes. AI Pro and AI Pro Max can boost water from a tank or self-prime from a well up to 9.5 meters.

Yes. Certain models support optional timing functions to automatically fill water tanks.

The AI series is backed by patented electronic pressure technology, high-quality materials, and strict quality control — ensuring stable and durable performance.
