Aqua Master Tools - C20 Dual-Channel Peristaltic Dosing Unit – 2-Pump Modular EC Fertilizer Injector for Automated Hydroponic Nutrition Systems
Streamline your fertilizer injection workflow and build a highly dependable nutrient-delivery loop with the Aqua Master Tools C20 Dual-Channel Peristaltic Dosing Unit. Explicitly engineered for the rigorous demands of commercial greenhouse operations, vertical indoor farms, and advanced hydroponic facilities, this premium industrial dosing station features **two independent peristaltic pumps dedicated solely to electrical conductivity (EC) asset management**. Many standard injection systems struggle with modern multi-part fertilizer programs, forcing facility technicians to pre-mix concentrated parts or handle messy manual dosing. The C20 resolves this operational hurdle by delivering automated, isolated handling of two distinct liquid nutrient lines, with each high-efficiency pump moving fluid at a calibrated rate of **1.5 mL per second**. To protect sensitive root structures from chemical shock and preserve the balance of your growing medium, this unit is designed strictly for fertilizer injection and is not intended for corrosive pH-altering acids or bases. Built for ultimate facility scalability, the C20 features a flexible, plug-and-play UTP interface. It can be wired directly into your master controller to automate a basic two-part fertilizer recipe, or it can serve as a seamless hardware expansion for a C30 unit to establish a comprehensive five-part commercial blending manifold. Shipped as an installation-ready kit, the C20 comes complete with two 3-meter coils of chemical-resistant transport tubing, a 150cm UTP data sync cable for instant controller communication, and a dedicated power adapter—giving your cultivation team everything required to maintain flawless crop nutrition round after round.
Best For: Automated injection of 2-part liquid fertilizer recipes, expanding existing multi-pump blending manifolds, and establishing scalable, isolated nutrient delivery lines in professional cultivation layouts.
Key Features & Technical Advancements
- Dual Independent Peristaltic Drives: Features two separate, high-precision roller assemblies that let you run two distinct liquid fertilizer lines simultaneously with zero cross-contamination.
- Calibrated 1.5 mL/s Displacement: Driven by constant-velocity motors that deliver exactly 1.5 mL per second per pump, ensuring highly repeatable, precise nutrient blending across every feeding cycle.
- Multi-Pump Hardware Daisy-Chaining: Designed with a versatile UTP interface that can function as a standalone 2-line injector or link into a central C30 module to scale your infrastructure up to 5 nutrient channels.
- Zero-Contact Chemical Isolation: The heavy-duty rollers compress the flexible internal tubing to advance fluids, keeping concentrated mineral salts isolated from the mechanical pump parts to maximize equipment lifespan.
- Dedicated Fertilizer Optimization Profile: Specifically engineered to handle concentrated liquid crop nutrients, making it the ideal hardware anchor for automated multi-part A and B reservoir management.
- Complete Professional Installation Kit: Unbox and deploy immediately with the included dual 3-meter chemical-resistant transport lines, a 150cm UTP data patch link, and a dedicated power adapter.

Advanced Pump Configuration & Substrate Coordination Tips
- Precise Multi-Part Recipe Management: To maximize fertilizer uptake and prevent leaf damage, use the C20 to inject concentrated nutrients evenly, eliminating sudden chemical spikes. When running standard commercial A and B formulas, set your master controller to trigger both pumps proportionally. This keeps your overall solution stable and locked into the target EC window (e.g., 1.4 mS/cm for vegetative growth, scaling to 2.0 mS/cm for peak production) without risking high-salt tip burn or root-zone imbalances.
- Root-Zone Hydration and Substrate Coordination: Delivering a perfectly blended nutrient solution around the clock ensures your root systems grow vigorously without salt stress. For uncompromised drainage, high structural aeration, and excellent water retention, use a high-porosity 70/30 blend of Coco Coir and Horticultural Perlite. To maintain uniform moisture profiles across your entire bench layout, feed your plants using lines pressurized by a heavy-duty Plont PPH Submersible Pump managed by an automated digital shot-timer.
- Preventing Siphon Hazards and Managing Line Placement: When plumbing your C20 pump into a batch tank, always guard against accidental siphoning. If the end of your discharge tube sits below the fluid level of your fertilizer concentrate bottle, liquid can crawl through the lines naturally, over-dosing your reservoir and causing severe root burn. Always mount your chemical storage bottles lower than the main reservoir injection points, and ensure the discharge tube hangs cleanly above the maximum water line of your batch tank to create a physical air gap.
- Peristaltic Squeeze Tube Maintenance Protocols: Because peristaltic pumps rely on mechanical rollers constantly compressing a flexible hose to move fluids, that internal squeeze tubing is subject to wear and stretching over time. Inspect the internal pump head assembly every crop cycle. Check for micro-cracks, hardening, or salt crusts along the tube wall, and wipe down the rollers to ensure smooth operation. Replacing the internal squeeze hose annually maintains your exact 1.5 mL/s delivery calibration and completely eliminates the risk of leaks on your facility floors.
Ideal For (Uses)
- Automated 2-Part Nutrient Delivery: The ideal dual-channel solution for hydroponic growers looking to automate the injection of premium multi-part commercial liquid crop inputs.
- Scalable Fertigation Rack Expansion: Perfect for facilities wanting to expand a C30 system to handle two extra feeding lines, organic boosters, or specialty additives.
- Commercial Facility Infrastructure Management: An exceptional spare component choice for large greenhouse operations and automated indoor farms looking to keep extra, plug-and-play modular pumps on hand to eliminate unexpected maintenance downtime.

Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
