Product Overview

This 750W, 48V DC solar surface pump series is designed for agricultural irrigation, livestock watering, tank filling, water transfer and remote off-grid water supply. The LBY models integrate an MPPT controller to improve the use of available solar power and simplify field installation.

Quick selection guide Choose by both required flow and total dynamic head—not by price alone. Pipe length, vertical lift, suction conditions and available solar voltage all affect actual output.

Choose the Right Model

LBY15/15-48/750-2

15 m³/h · 15 m head · 2 in outlet

Balanced flow and lift for drip irrigation, greenhouse watering, livestock trough filling and small-farm water transfer.

LBY25/12-48/750-3

25 m³/h · 12 m head · 3 in outlet

Highest-flow option for pond or tank transfer, field irrigation and applications with lower lift and larger pipework.

SIHF20/26-48/750-2

20 m³/h · 26 m head · 2 in outlet

Higher-lift option for elevated storage tanks, longer delivery lines and uneven terrain. Confirm its electrical operating range before solar-array sizing.

Engineering note: SIHF electrical-range data was not included in the supplied catalogue page. Actual performance varies with solar input, total dynamic head, pipe diameter and length, suction conditions and installation quality.

Typical Applications

Field & drip irrigation
Move water from a pond or tank to crops and irrigation lines.

Greenhouses & nurseries
Support scheduled watering where grid power is unavailable.

Livestock water supply
Fill troughs and storage tanks at farms and remote sites.

Pond & tank transfer
Transfer clean water between reservoirs, ponds and holding tanks.

Remote water supply
Provide practical pumping for off-grid and unreliable-grid locations.

Seasonal water transfer
Portable support for farm, garden and emergency water-moving tasks.

LBY solar surface pump used for off-grid agricultural irrigation — Typical off-grid irrigation application. Solar panels, pipework, fittings and water-storage equipment are supplied according to the project quotation.

How the Solar Pump System Works

Solar array → MPPT controller → surface pump → storage tank or irrigation line. The controller manages solar input and drives the pump during suitable sunlight conditions. Solar panels, mounting hardware, pipework, fittings, valves and storage tanks are not included unless they are specifically listed in your quotation or order.

DC solar pump connection from solar panel through controller and LBY surface pump to water tank — System principle: solar array → DC display controller → LBY surface pump → water tank or irrigation line.

Controller Display & Polarity

Confirm positive and negative polarity before connection. The display module shows operating voltage and current; wiring must follow the supplied controller labels and the approved solar-array voltage range.

Built-in DC controller voltage and current display with input and output polarity — Controller reference from the supplied catalogue. Verify input/output polarity before installation.

LBY Performance Curves

Complete LBY solar surface pump flow and head performance curves — Complete source-catalogue curves. Numbered operating points correspond to the LBY model table; confirm the selected model against required flow and total dynamic head.

Before You Order

Required flow: expected water volume per hour or per day.
Total dynamic head: vertical lift plus pipe-friction loss.
Water source: pond, tank, canal or other clean-water source; include suction lift and water level.
Pipework: diameter, total length, bends and outlet height.
Solar input: panel quantity, array voltage and open-circuit voltage (VOC).
Delivery details: destination country, quantity and whether you need a pump-only or complete-system quotation.

For project sizing, send us the six items above before ordering. We will check model fit and solar-array compatibility. Listed prices are in USD and exclude taxes, import duties and destination charges unless otherwise stated at checkout.

Ordering Process

1. Select a model
Compare flow, head and outlet size.

2. Confirm site data
Check head, suction, pipework and solar VOC.

3. Place order or request a quote
Buy the pump online or ask for project sizing.

4. Shipping & support
We confirm dispatch and provide installation guidance.

Package & Warranty

For LBY models, the standard product information covers the pump with a 1 metre cable. Please confirm the exact package contents before payment, especially for complete-system or OEM/ODM orders. The pump carries a 1-year limited product warranty, subject to correct installation and operation within the specified electrical and hydraulic limits.
