Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998 with over 20 years of export experience. Our Industrial Swimming Pool Sand Filter is specifically designed for demanding environments like water parks, where high flow rates and reliable filtration are critical. With a 48-inch tank, 3HP pump, and 60 m³/h capacity, this system ensures crystal-clear water while minimizing maintenance through PLC-controlled automatic backwash.
Built for heavy-duty commercial use, this filter combines robust construction with intelligent automation. The PLC controller monitors pressure differentials and initiates backwash cycles automatically, extending filter runs and reducing water waste. Whether you're managing a large aquatic facility or a resort pool, this unit delivers consistent performance and long service life.

Frequently Asked Questions
-
How often does the automatic backwash occur?
The PLC controller triggers backwash based on pressure differential (typically when pressure rises 10 psi above clean pressure) or at a set time interval (e.g., every 24 hours). You can adjust parameters via the touch screen. -
What type of sand should I use?
We recommend #20 silica sand with a grain size of 0.45–0.55 mm. For water parks with high turbidity, you may use a multi-layer media (e.g., sand + gravel) – we can advise on the best configuration. -
Can this filter handle salt water?
Yes, the FRP tank and PVC/polypropylene components are corrosion-resistant. If you choose the stainless steel option, it is 316L grade for saltwater durability. -
What is the expected lifespan of the filter tank?
FRP tanks typically last 10–15 years with proper maintenance. Stainless steel tanks can last even longer. The internal components (valve, seals) may require replacement after 5–8 years. -
Is the PLC control system compatible with remote monitoring?
Our standard PLC supports Modbus RTU; an optional GSM/WiFi module can be added for remote access. Please inquire for integration details. -
What is the warranty coverage?
The 2-year warranty covers manufacturing defects in the tank, valve, pump, and PLC controller. Normal wear items (seals, gaskets) are excluded. We provide spare parts at cost after warranty. -
How long does installation take?
Typically 1–2 days for a standard setup. The unit comes pre-assembled with the multiport valve mounted. Your plumber needs to connect inlet/outlet pipes, electrical, and add sand. -
What is the minimum flow rate required for backwash?
For effective backwash, the pump should deliver at least 50 m³/h (ours is 60 m³/h). If your system has lower flow, we can adjust the valve or recommend a booster pump.
