ZIRI SHF5B Surface Solar Pump 1HP 21m 21m³/h

Product Description

The ZIRI SHF5B Surface Solar Pump is a 1 HP direct current centrifugal pump designed to move large volumes of water using solar energy, maintaining installation simplicity and high reliability. It offers a maximum flow rate of 21 m³/h and a head of 21 m, an ideal balance for swimming pools, large-capacity tanks, medium/large surface irrigation, and rapid transfers. Its internal MPPT controller optimizes power capture from the photovoltaic generator, stabilizing operation under irradiance variations and reducing the number of external components.

Main Features

• High flow with useful pressure: 21 m³/h and up to 21 m head.
• DC working range: 80–150 VDC with integrated MPPT for maximum efficiency.
• Maximum open-circuit voltage (Voc) allowed: 180 V (size the string to avoid exceeding this in cold conditions).
• Maximum suction 6 m; centrifugal design suitable for continuous service with clean water.
• Professional construction: cast body and motor support; copper alloy impeller.
• 2” hydraulic connections to minimize losses and facilitate high flow rates.

Advantages or Benefits

• 1 HP solar pump solution that prioritizes flow, ideal for swimming pools, ponds, and higher-demand irrigation.
• Simplified installation: the internal MPPT manages the PV generator and improves start-up/performance with clouds and partial shading.
• Almost zero energy cost and reduced maintenance thanks to metallic materials and operation with clean water.
• Easy automation with presscontrol/pressure switch and expansion tank for stable pressure in the internal network.
• Reliability and robustness for daily use in residential, agricultural, or service environments.

Purpose or Applications

Filtration and recirculation of swimming pools, filling/transferring tanks and ponds, sprinkler and drip irrigation of large plots, support for cleaning and washing, and pressure boosting in internal networks of estates or tourist facilities. Suitable for intakes from ground-level tanks or shallow wells up to 6 m suction.

Technical Specifications

Compatibilities

Direct compatibility with photovoltaic generators whose operating point remains within 80–150 VDC and whose string Voc does not exceed 180 V. With integrated MPPT, no external controllers are required.

Compatible accessories: 2” foot valve and filter, check valve, presscontrol/pressure switch, expansion tank, DC protections (circuit breaker and SPD), solar cabling sized for current/distance, level switch, and 2” fittings.

The ZIRI SHF5B provides high flow, simple installation, and great reliability, making it an excellent choice for solar systems seeking to move large amounts of water efficiently and with low operating cost.
