Grech CPA15000 Auto Cleaning Pressurized Koi Pond Filters

Grech CPA15000 Auto Cleaning Pressurized Koi Pond Filters (15000 L/H) New pond filter generation: Bio pressure pond filter CPA-15000 Characteristics: Indicator for pollution High flow rate Optimum development of biological pond filter Easy and uncomplicated bio-pressure pond filter-system This system provides fast and reliably clear water Easy backwashing (by flipping a switch) Different filter materials (special filter foams) Advantages: Mechanical and biological pressure filter with integrated UVC-clarifier. All connections and technology are in the lid/cover, the filter can be buried to lid for concealment without difficulty. Flush back function with maintenance indicator. Cleaning and maintenance: The water can be pumped to a higher lying waterfall and then led back into the pond. The annual maintenance is limited to checking the filter media and the UV-lamp. The filter has a modern flush back function that can be adjusted by means of a switch with four functions. With the switch you have the following possibilities for setting: The EasyClean flush back function: • Switch position "Filter" Normal operation - the water passes through the pressure pond filter with the help of a pond pump and returns cleanly into the pond. • Switch position "Clean" Cleaning mode - By turning the switch the motor that is integrated in the top of the filter is switched on and makes the filter sponges rotate in the inner of the pond filter and cleans them from the coarse dirt without opening the pond filter. During the cleaning operation the dirty water is drained by an additional connection and can be used for example for garden irrigation. Filter Placement: The filter is placed at the pond side and by means of a a suitable pump (not included in delivery) connected with the water. The water circulates through the filter and the UV-device and after being cleaned is led again into the pond. Fundamental Functionality: Pond filter combine the mechanical and biological cleaning. Microorganisms settle on the filter material and remove germs and bacteria from the water. By mechanical filtering, suspended particles and dirt remain in the pond filter and by this means no longer return to the pond water. It takes about 4-6 weeks, until Filter Bacteria have sufficiently colonized the bio pond filter. Only thereafter t is advisable to switch on a UVC Pond Clarifier. Starter bacteria help to shorten the start-up phase of a new filter. Starter bacteria refer to microorganisms especially grown in a laboratory. By adding them, you can shorten the start-up phase considerably. Bacteria are active above a temperature of approximately 10°-12°C, the pond filter´s temperature should exceed 40°C. So the pond filter should be placed in the shadow and not be exposed to direct sunlight. UVC-pond clarifiers irradiate the water in a flow-through reactor with UV rays. The UV-C radiation destroys the swimming algae. The algae agglutinate to large particles and ca be easily removed by means of mechanical filtering. Our UVC clarifiers modify the tertiary and the quaternary structure of the algae proteins by means of UV-radiation. This means the destructions of the algae which can be removed from the water by pond filters.

Fountain Nozzles

Foam jet Fountain Nozzle

Transform Your Water Feature with Foam Jet Fountain Nozzles: The Water Level Independent Solution Water fountains have long been the centerpiece of gardens, courtyards, and public spaces, creating mesmerizing displays that captivate viewers with their graceful water patterns. Among the various fountain nozzle types available today, the Foam Jet Fountain Nozzle stands out as a revolutionary design that offers both aesthetic appeal and practical functionality, particularly due to its water level independent operation. What Makes Foam Jet Fountain Nozzles Special? The Foam Jet fountain nozzle creates a distinctive water pattern that combines the beauty of traditional fountain jets with the unique characteristic of producing aerated, foamy water streams. This innovative design results in spectacular white, frothy water columns that dance upward, creating an eye-catching display that's both elegant and dynamic. Unlike conventional fountain nozzles that rely heavily on consistent water levels and pressure, foam jet nozzles are engineered to maintain their performance regardless of minor fluctuations in water depth. This water level independence makes them an ideal choice for various fountain applications, from residential water features to large commercial installations. The Science Behind Water Level Independence Traditional fountain nozzles often struggle with performance variations when water levels change due to evaporation, wind, or seasonal adjustments. The foam jet nozzle's innovative internal design incorporates advanced hydraulic engineering that compensates for these variations automatically. The nozzle's internal mechanism includes precision-machined components that create a venturi effect, drawing air into the water stream while maintaining consistent flow patterns. This air injection process not only creates the characteristic foamy appearance but also helps stabilize the water jet's performance across different operating conditions. Key Benefits of Foam Jet Fountain Nozzles Consistent Performance The water level independent design ensures your fountain maintains its stunning visual appeal throughout the day and across seasons, requiring minimal maintenance and adjustment. Enhanced Visual Impact The aerated water creates brilliant white foam patterns that are particularly striking against dark water or during evening illumination with fountain lights. Reduced Maintenance With less sensitivity to water level variations, these nozzles require fewer adjustments and interventions, making them perfect for busy commercial environments or low-maintenance residential settings. Versatile Applications From intimate garden ponds to grand public fountains, foam jet nozzles adapt to various scales and settings while maintaining their distinctive performance characteristics. Energy Efficiency The air injection process reduces the actual water flow required to create impressive displays, potentially lowering pump energy requirements and water consumption. Installation and Design Considerations When planning your fountain project with foam jet nozzles, consider these important factors: Pump Selection: While these nozzles are water level independent, proper pump sizing remains crucial for optimal performance. Consult with fountain professionals to determine the right pump capacity for your specific installation. Basin Design: The fountain basin should accommodate the nozzle's spray pattern while allowing for proper water circulation and filtration. Lighting Integration: Foam jet patterns are particularly stunning when combined with underwater LED lighting systems, creating dramatic nighttime displays. Wind Considerations: While the foam pattern is stable, consider prevailing wind patterns in your location to minimize water loss and maintain the intended visual effect. Material Quality and Durability High-quality foam jet fountain nozzles are typically constructed from corrosion-resistant materials such as brass, stainless steel, or specialized bronze alloys. These materials ensure longevity in outdoor environments while maintaining consistent performance over time. The precision manufacturing required for proper air injection and water level independence demands careful attention to internal tolerances and surface finishes. Quality nozzles feature smooth internal passages that prevent clogging and maintain optimal flow characteristics. Maintenance Tips for Optimal Performance While foam jet nozzles are designed for low maintenance, following these simple guidelines will ensure years of reliable operation: Regular Cleaning: Remove any debris or mineral buildup from the nozzle openings monthly Water Quality: Maintain proper water chemistry to prevent scaling and corrosion Seasonal Preparation: Follow manufacturer guidelines for winterization in freezing climates Professional Inspection: Schedule annual professional maintenance to ensure optimal performance Creative Applications and Design
