Grundfos pressure group JP 5-48

The Grundfos JP 5-48 centrifugal pump, reference 99458769, is a self-priming single-stage pump designed to meet various domestic water supply applications. Ideal for pumping water from wells, tanks, or underground sources, this compact and robust pump is an efficient and durable solution to ensure a reliable water supply at home. Thanks to its stainless steel design and self-priming technology, the Grundfos JP 5-48 offers outstanding performance in terms of durability, ease of use, and corrosion resistance.

Applications and versatility:

The Grundfos JP 5-48 is designed for domestic groundwater consumption applications. Its ability to lift water from deep wells or tanks, with a suction height of up to 8 meters, makes it the ideal choice for homes needing to extract water from underground sources. Its self-priming design allows it to manage a combination of air and water until it reaches a full pumping condition, ensuring a continuous and uninterrupted flow.

The pump is suitable for a wide variety of applications, such as water supply for garden irrigation, filling tanks, or use in domestic water systems. Its nominal flow rate of 5 m³/h and a lifting height of 27.83 m enable this pump to meet the needs of a reliable water supply system for homes or small agricultural properties.

Durability and corrosion resistance:

One of the main advantages of the Grundfos JP 5-48 is its stainless steel body (EN 1.4301, AISI 304), which ensures excellent corrosion resistance, even in environments with high humidity levels or in continuous contact with water. Additionally, its composite impeller (PPO-20GF) ensures that the pump is wear-resistant and offers reliable performance over time.

The application of electrophoretic painting on the pump housing adds an extra layer of protection, ensuring that the pump maintains its performance even in adverse conditions. This design guarantees a long lifespan and smooth operation, reducing the need for maintenance and costly repairs.

Advanced self-priming technology:

The Grundfos JP 5-48 is equipped with an integrated ejector with guide vanes, which enhances the self-priming properties of the pump. This means that the pump can lift water from below the inlet level without issues, which is especially useful for deeper water sources or when the system requires efficient self-priming. Thanks to this feature, the pump is capable of providing stable performance even in challenging pumping conditions.

Thermal protection and efficient motor:

The JP 5-48 pump features an integrated thermal protection, which automatically stops the pump operation if the motor overheats, protecting the equipment and prolonging its lifespan. Additionally, the motor is equipped with oversized, sealed, and permanently lubricated ball bearings, ensuring quiet operation and no need for frequent maintenance.

The motor of the Grundfos JP 5-48 is asynchronous and air-cooled, which ensures effective heat dissipation during operation. With a nominal power of 1 kW and a nominal speed of 2870 rpm, the pump provides optimal performance for domestic applications, allowing for efficient water pumping with optimized energy consumption.
