Grundfos JP 5-48 Pressure Booster Set

The Grundfos JP 5-48 centrifugal pump, reference 99458769, is a single-stage self-priming 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 underground water consumption applications. Its ability to lift water from deep wells or tanks, with a suction height of up to 8 metres, makes it the ideal choice for homes that need to draw water from underground sources. Its self-priming design allows it to handle a combination of air and water until it reaches a fully primed condition, ensuring a continuous and uninterrupted flow.

The pump is suitable for a wide variety of applications, such as supplying water 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 allow this pump to meet the needs of a reliable water supply system for the home 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 the pump is wear-resistant and offers reliable performance over time.

The electrophoretic paint application on the pump housing adds an extra layer of protection, ensuring the pump maintains its performance even in adverse conditions. This design guarantees a long service life and trouble-free 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 pump's self-priming properties. This means 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 can offer stable performance even in challenging pumping conditions.

Thermal protection and efficient motor:

The JP 5-48 pump features integrated thermal protection, which automatically stops the pump operation if the motor overheats, protecting the equipment and extending its service life. Additionally, the motor is equipped with oversized, sealed, and permanently lubricated ball bearings, ensuring quiet operation without frequent maintenance requirements.

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 offers optimal performance for domestic applications, allowing efficient water pumping with optimised energy consumption.
