Product Description
Discharge Hose for SEKO Tekna EVO Pump, PE 4x6 mm (Part No. 0000090002)
Calibrated Polyethylene Dosing Tube – Guaranteed Precision and Safety for Car Wash Chemical Delivery
The professional-grade 4x6 mm discharge hose (Part No. 0000090002) is a premium fluid-handling component specifically engineered to operate on the high-pressure delivery side of SEKO Tekna EVO electromagnetic dosing pumps (including AKS, AKL, TPG, and TPR series). Extruded from high-density, specialized Polyethylene (PE), this tubing features the exact rigid structural profile necessary for precision chemical injection. Within BKF self-service car wash systems, this hose is responsible for transferring highly concentrated chemicals—such as pre-wash shampoos, active foams, polymers, and drying waxes—directly from the dosing pump head to the downstream water manifolds or water-injection points. Selecting this original calibrated PE hose eliminates the risk of dosing inaccuracies, pressure drops, or chemical leaks caused by tube expansion.
Key Technical Features and Operational Advantages:
- Premium Rigid Polyethylene (PE) Formulation: Unlike flexible tubing, this rigid PE tube does not swell, pulse, or balloon under the cyclic pressure spikes generated by the pump’s stroke cycle. This guarantees superior dosing repeatability and linear chemical distribution.
- Exact 4x6 mm Calibration: With a perfectly consistent 4 mm internal diameter and 6 mm external diameter, the tube ensures a 100% hermetic, leak-free compression fit into the original SEKO pump heads, foot filters, and injection valves.
- Maximum Chemical Immunity: The industrial PE matrix is completely inert and resistant to highly concentrated surfactants, aggressive alkaline vehicle shampoos, hyper-foams, and acidic wheel cleaners or scale removers.
- Environmental Stress Crack Resistance (ESCR): Enhanced structural elasticity prevents the tube from cracking or splitting near connection nuts or tight bends where mechanical stress and compression are highest.
- Heavy-Duty Plantroom Longevity: Built to withstand the harsh conditions of car wash technical rooms, showing full resilience to high humidity, chemical fumes, temperature fluctuations, and localized UV exposure.
Primary Application Areas:
- Self-Service Car Wash Dosing Blocks: Secure connection between the discharge valve of the SEKO Tekna EVO pump and the water injection point for chemical delivery.
- Water Treatment & Reverse Osmosis Systems: Injection lines feeding antiscalant chemicals, biocides, and pH regulators (acids or alkalis) into the main RO water stream.
- Industrial Chemical Dispensing Loops: Any automated processing assembly requiring precision volumetric dosing via micro-tubing.
Frequently Asked Questions (FAQ)
Why must a rigid PE hose be used on the pump's discharge side instead of a flexible PVC hose?
Solenoid-driven dosing pumps operate via a rapid, pulsating stroke action. If a flexible PVC hose (which is typically reserved for the suction side) is installed on the discharge line, it will expand and contract with each pulse. This elasticity cushions the volumetric displacement, leading to severe dosing errors and chemical waste. The rigid PE hose keeps its structural volume intact under pressure, ensuring that 100% of the metered chemical is cleanly discharged into the system.
Does this 4x6 mm PE tube fit other brands of chemical dosing pumps?
Yes. While this hose is an original factory spare part designed for the SEKO Tekna EVO series inside BKF wash structures, the 4x6 mm size (4 mm inside, 6 mm outside) is an international standard within fluid automation. It can be used seamlessly on alternative dosing equipment from manufacturers like Aqua, Etatron, Emec, and Iwaki, provided they feature matching 4x6 mm compression connectors.
What is the correct way to cut and install this PE tube to guarantee a watertight seal?
The PE tube must be cut using a very sharp utility knife or a specialized plastic pipe cutter, ensuring the cut is exactly perpendicular (90 degrees) to the tube length. Never use standard scissors, as they deform and flatten the circular end, making it impossible to slide over the inner cone adapter properly and leading to high-pressure leaks. During installation, slip the compression locknut onto the tube, firmly press the tube end fully over the valve cone, and hand-tighten the nut securely (a small turn with a wrench can be applied if necessary, but avoid overtightening).
