LSP DC Brushless Swimming Pool Solar Pump

Model Interpretation:
LS: Usually represents "Vertical/Centrifugal" or "DC".
P: Represents "Pool" or "Pump".

Core Configuration: Horizontal/side-mounted DC brushless centrifugal pump, usually with large diameter inlet and outlet ports.
Working Method: It is a surface pump, installed in the equipment room next to the swimming pool or on the ground. It uses its powerful circulation capacity to pump pool water into the filter sand tank, filter it clean, and then return it to the pool.
Core Working Principle: Magnetic drive + Permanent magnet brushless motor
The biggest difference between the LSP series pool pump and ordinary water pumps lies in its sealing and corrosion resistance:
Power Source: Uses a DC brushless motor (BLDC). Compared with traditional single-phase AC motors, it is significantly more energy-efficient (30%-50% energy saving) and has adjustable speed.
Sealing Technology (Key):
Many high-end LSP series pumps use magnetic drive (seal-less) technology. Ordinary water pumps rely on mechanical seals to prevent leakage, which are prone to wear and leakage after long-term operation; while magnetic pumps use magnetic coupling transmission, completely isolating the motor and pump body, fundamentally eliminating the risk of leakage.
Corrosion-Resistant Design: Swimming pool water contains chlorine (disinfectant) and other chemicals, which are corrosive. The pump body of the LSP series usually uses corrosion-resistant engineering plastics (such as ABS, RPP) or 304 stainless steel, and the impeller is usually made of modified plastic or copper to adapt to this special water quality.
Core Features: Corrosion resistance, low noise, long lifespan

Feature Detailed Description
Designed for swimming pools The pump body flow channel is wide, allowing small suspended impurities (such as hair, leaf debris) to pass through without clogging.
Chemical corrosion resistance The parts in contact with water (pump casing, impeller) are made of chlorine-resistant and acid-alkali resistant materials, which will not rust or pollute the water quality.
Quiet operation Due to the use of a brushless motor and optimized hydraulic model, the operating noise is extremely low (usually below 40 decibels), and will not disturb your leisure time by the pool.
Intelligent control Supports PWM speed control or analog signal speed control. You can adjust the appropriate flow rate according to the size of the swimming pool and filtration needs, ensuring both filtration effect and energy saving. 

Typical Application Scenarios
The LSP series is a specialized equipment for water treatment circulation systems:
Residential/Villa Swimming Pools:
Used as the main circulation pump for private villa swimming pools, operating 24 hours a day to maintain clear water quality.
SPA/Jacuzzi:
Drives water flow in SPAs, working with the bubble system to provide massage and hydrotherapy effects.
Landscape Ponds/Fountains:
Used in landscape ponds in parks or courtyards to maintain water flow and prevent stagnation and odor.
Small Fish Ponds/Aquaculture Farms:
Used in water circulation and filtration systems for ornamental fish ponds.

Selection and Usage Recommendations
Calculating Pool Volume:
The key to pump selection is flow rate. Generally, the pool water should be circulated every 6-8 hours.
Formula: Total pool water volume (tons) ÷ Circulation time (hours) = Required flow rate (tons/hour).
For example: A 50-ton swimming pool that needs to be circulated every 8 hours requires a pump with a flow rate of approximately 6-7 tons/hour.
Head Requirements:
The head of a swimming pool pump is mainly used to overcome the resistance of the filter sand tank and pipes. Typically, a pump with a head of 10-15 meters is sufficient for home swimming pools.
Suction Method:
Swimming pool pumps are usually installed using a "suction" method, meaning the pump is positioned slightly above or at the same level as the pool water surface. Due to atmospheric pressure limitations, the vertical distance from the pump to the water surface should generally not exceed 5 meters.
Protection Rating:
Since it is installed outdoors or in a humid environment, it is essential to confirm the waterproof rating of the motor (IP68 recommended) to prevent moisture damage and short circuits.

The LSP series is the "water quality guardian" in the solar water pump family. If you need to maintain a swimming pool, SPA, or landscape pond, and want equipment that is quiet, rust-proof, and energy-efficient, then the LSP series is a more professional and reliable choice than general-purpose surface pumps (such as LSZ/LHF).
