Application

Residential water supply from deep wells for household needs like drinking, cooking, and sanitation.
Irrigation systems for lawns, gardens, and small-scale agricultural operations.
Boosting water pressure in multi-story buildings or remote locations.
Providing a consistent water source for livestock watering on farms and ranches.
Supplying water for small-scale industrial processes or equipment cooling.
Filling water storage tanks or reservoirs for emergency preparedness or backup supply.
Dewatering applications in construction sites, mines, or quarries where groundwater accumulates.

Application Limits

Maximum Ambient Temperature: < 40°C (104°F) These deep well pumps are designed to operate effectively in ambient temperatures up to 40°C. Exceeding this temperature can lead to overheating, reduced efficiency, and potential damage to the pump components.

Maximum Permissible Sand Content: 100g/m³ The pumps can handle water with a sand content up to 100 grams per cubic meter. Higher concentrations of sand particles can accelerate wear on the impellers, seals, and other internal parts, leading to premature failure.

Hydrogen Sulfide and Chloride Ion Content:

Hydrogen Sulfide: Up to 1.5mg/L
Chloride Ions: Up to 400mg/L These pumps are suitable for water sources with moderate levels of hydrogen sulfide (up to 1.5 milligrams per liter) and chloride ions (up to 400 milligrams per liter). Higher concentrations of these compounds can cause corrosion and deterioration of the pump materials over time.

pH Range: 6.5 to 8.5 The pumps are designed to handle water with a pH range of 6.5 to 8.5, which is considered slightly acidic to slightly alkaline. Operating with water outside this range can lead to chemical attacks on the pump materials and potential scaling or deposit buildup.

Maximum Depth Below Static Water Table: 20m These pumps can be installed up to 20 meters below the static water table level. This depth rating ensures reliable performance and sufficient net positive suction head (NPSH) for optimal pump operation.

By adhering to these specifications, the deep well pumps can maintain optimal efficiency, longevity, and performance, minimizing the risk of premature failure or damage due to adverse water conditions or environmental factors.

FAQ

What is the maximum depth this pump can be installed at?

This deep well pump is rated for a maximum installation depth of 20 meters (65 feet) below the static water table level.

Can this pump handle sandy water?

Yes, the pump can handle water with a sand content of up to 100 grams per cubic meter without issue.

Is this pump suitable for water with high mineral content?

The pump can handle water with moderate levels of chloride ions (up to 400mg/L) and hydrogen sulfide (up to 1.5mg/L). Higher concentrations may lead to corrosion and accelerated wear.

What is the maximum ambient temperature this pump can operate in?

The maximum ambient temperature for this deep well pump is 40°C (104°F). Operating at higher temperatures can cause overheating and potential damage.

Can this pump be used for irrigation purposes?

Absolutely, with a flow rate of 24 gallons per minute, this pump is well-suited for residential irrigation systems, gardens, and small agricultural operations.

What is the pH range this pump can handle?

The pump is designed to handle water with a pH range of 6.5 to 8.5, which covers slightly acidic to slightly alkaline conditions.

How do I determine the appropriate size pump for my well?

Factors like well depth, water demand, and system requirements need to be considered. Consult a professional or refer to the manufacturer’s sizing guidelines.

Does this pump require a control box or variable frequency drive?

This specific model is a single-speed pump. Depending on your application and requirements, a control box or VFD may be recommended for optimal performance and energy efficiency.
