The Aldous metering pump specified here has a flow rate range of 0.48–20.00 L/H according to the product specification. If you require higher flow rates, please contact the supplier — other models in the product line may support larger capacities.
The pump's pressure range is listed as 1.0–8.2 bar, with 8.2 bar being the maximum discharge pressure for the specified model.
It uses a high-performance 'PH type' pump head designed for durability in chemical dosing applications. This design helps improve resistance and longevity when handling aggressive liquids such as acids, but compatibility should still be confirmed for each chemical.
Yes — the pump is described as an acid metering pump and is intended for chemical liquids. However, always verify chemical compatibility with the pump head and wetted materials for your specific chemical and concentration before use.
The single package size is 40 x 30 x 20 cm. The pump weight is approximately 4 kg, and the single gross weight (packaged) is listed as 8.000 kg.
Typical applications include water treatment, chemical transfer, accurate dosing of acids and other chemical liquids, laboratory and research dosing, and industrial cleaning/maintenance tasks.
Yes. This is a chemical membrane (diaphragm) metering/dosing pump, which uses a membrane to isolate the drive mechanism from the process fluid.
A specific numerical accuracy is not provided in the supplied specification. Dosing precision depends on the model and operating conditions; please contact the supplier for calibration/accuracy data for the exact model you plan to use.
Routine maintenance typically includes inspecting and replacing the diaphragm, check valves, and tubing as needed and checking for leaks. Spare parts availability (diaphragms, seals, valves) should be confirmed with the supplier or authorized service center.
Yes. The product listing indicates it includes a video outgoing inspection and a machinery test report for quality assurance.
Electrical requirements and control options are not specified in the provided data. These details (voltage, frequency, motor type, speed control, remote control/interfaces) vary by model — contact the manufacturer or supplier for model-specific electrical and control information.
Select a model based on required flow rate (L/H), discharge pressure (bar), chemical compatibility, and any control or installation needs. Provide the supplier with application details (fluid type/concentration, temperature, required flow/pressure, and duty cycle) for assistance.
The specification does not list standard accessories. Typical deliveries may include the pump unit and test documentation; fittings, tubing, foot valves, or mounting hardware may be optional. Confirm included accessories with the seller before purchase.
Installation requirements depend on the site and model. General recommendations: mount on a stable surface, secure fittings and tubing to avoid strain, ensure venting/drain provisions as needed, and follow the manufacturer's installation manual. For critical applications, have a qualified technician perform installation.
Warranty and after-sales service terms are not provided in the supplied specifications. Contact the supplier or Huamo (brand) for warranty duration, service agreements, and authorized service centers in your region.
