DP300-PH is the pH control model of CyberSync Core-Plus series automatic dosing pump, matched with dedicated pH probe to realize full-automatic pool pH balance regulation. The LED digital screen displays real-time pool pH value within measuring range pH4~pH10. When the water pH value exceeds the ideal swimming range, the pump will automatically add muriatic acid or sulfuric acid to lower pH and stabilize water quality.

CyberSync Core DP300 is the entry-level versatile peristaltic dosing pump for household swimming pools. Equipped with clear LED digital display and simple operation buttons, users can manually adjust dosing flow rate effortlessly to realize precise chemical concentration control. It adopts mature peristaltic pump structure, supports stable max 3 L/h dosing rate under 1.5 bar working pressure, with universal 110-240V wide voltage design to fit global household power supply. Made of chemical & UV resistant materials, this compact wall-mounted dosing pump provides cost-effective water quality maintenance solution for small residential pools, effectively reducing manual chemical addition work.

EM4420 eyeball jet has two versions for imperial and metric pipelines, with a steady 240 L/min flow rate. The rotatable eyeball core freely adjusts water flow angle to eliminate dead water zones. Featuring a flush-mounted Ø87mm cover and unified G2A threaded base, it adopts corrosion-resistant pool plastic. Safe for swimmers without protruding edges, it fits concrete and vinyl liner pools for residential and commercial circulation systems.

EM2855 vacuum lock safety wall fitting is a safety suction wall port designed for pool vacuum cleaning equipment. It adopts flip-top safety lock cover design, which can automatically close the pipeline when the vacuum hose is pulled out to prevent dangerous vacuum suction. The product supports dual connection standards: 38mm solvent weld and G1.5A external screw thread, matching both metric and imperial pool pipeline systems. Its flow range is 150–240 L/min, compatible with most automatic pool cleaners and manual vacuum cleaning tools on the market. Made of chemical & UV resistant pool-grade plastic, compact embedded structure can be installed flush with pool wall without protruding edges, safe and beautiful for all pool types.

EM2841 and EM2841E are professional pre-embedded conduits exclusively developed for concrete swimming pools. Both versions adopt standard G2A screw thread design, supporting stable flow rate of 150–240 L/min. Two connection specifications are available: EM2841 fits 1.5” imperial & 50mm metric solvent pipes, while EM2841E only matches 50mm metric solvent pipes. Made of anti-corrosion pool-grade plastic, the integrated long-body structure can be buried together with concrete pouring, reserved for nicheless light installation and pool water circulation pipelines, with stable pressure resistance and long service life.

EM2832 series 1.5" main drain is a compact bottom suction fitting designed for small and medium swimming pools, split into two dedicated models: EM2832C for concrete pools and EM2832V for vinyl liner pools. The cover outer diameter is Ø220mm, total height 174mm, adopting concentric multi-layer grille anti-safety suction cover structure, which effectively prevents swimmers’ hair and limbs from being sucked. It adopts unified 1.5" internal thread connection port, with stable 150 L/min water flow to meet the circulation demand of small and medium-sized pools. Made of chemical & UV resistant pool-grade engineering plastic, it can be pre-buried synchronously during pool construction, with stable pressure resistance and long service life.

EM2824 Wall Return is a standard wall-mounted backflow fitting designed for swimming pool circulation systems. It features a circular slotted cover with wide water outlet area to deliver smooth, even backflow inside the pool. The series covers complete imperial inch and metric mm solvent weld connections with graded flow rates, perfectly matching various pool pipeline specifications. Made of pool-grade anti-corrosion plastic resistant to chlorine and UV rays, this fitting enables balanced pool water circulation, reduces dead water zones, and fits seamlessly on concrete pool walls for both new build and retrofit jobs.

EM2819 Gutter Drain is a professional pool overflow drainage fitting specially designed for infinity edge and concrete swimming pools. It adopts rectangular slotted cover design to efficiently collect overflow water from pool gutter system. Multiple imperial and metric solvent connection sizes are available with graded flow rate options to match different pool circulation pipeline demands. Made of high-quality chemical-resistant plastic, this drain is anti-UV and long-lasting under chlorinated pool water environment, realizing stable overflow drainage and balancing pool water level automatically.
