An Overview of Mechanically Actuated Metering Pumps
These pumps are designed to eliminate hydraulic oil for diaphragm actuation. Mechanically actuated pumps are a reliable solution for precise chemical dosing in different industries comprising water treatment and chemical processing. These pumps utilize worm gears, motors, drive shafts, and pistons to ensure efficient and reliable operation.
These pumps precisely injecting chemicals such as chlorine, coagulants, pH adjusters, and so on. With distinctive attributes like adjustable flow rates, manual stroke adjustments, and sturdy constructions, they offer versatility and reliability for critical chemical dosing tasks.
Important Features of Mechanically Actuated Pumps
These are some important features of mechanically actuated metering pumps based on their function.
- Drive Mechanism: These pumps function mechanically using components like worm gears, motors, or crankshafts to propel the pumping action.
- Stroke Adjustments: Several such pumps feature manual stroke adjustments, permitting operators to fine-tune the volume of liquid pumped per stroke.
- Adjustable Flow rates: Maintaining the required flow rates is important for accommodating different process requirements. Mechanically actuated metering pumps offer adjustable flow rates to offer flexibility in dosing applications.
- Calibration Mechanism: Calibration is an important aspect for any equipment to continue getting accurate readings. To uphold accuracy over time, these pumps feature a calibration mechanism that permits periodic adjustment of dosing precision.
- Pressure Relief Valve: These pumps have a pressure relief valve to shield against over-pressurization, thus ensuring safe and reliable operation.
- Check Valves: These are incorporated into the pump design to ensure one-way liquid flow, stop backflow, and preserve accurate dosing.
- Robust Construction Materials: Our metering pumps are constructed with durable materials like stainless steel, PVC, or reinforced plastics to endure corrosive chemicals and harsh operating conditions.

How to Choose the Correct Mechanically Actuated Metering Pumps?
While selecting a mechanically actuated chemical metering pump or dosing pump, it is essential to examine various technical and operational features that align with the particular requirements of your application. This ensures optimal performance and efficiency in your system. These are some important factors to consider during your selection process.
- Flow Rate and Precision: Choose a pump that delivers your desired flow rate with the required precision, which may be within 1% for most applications, to ensure accurate fluid dosing.
- Pressure Range: Make sure the pump can withstand the pressure range in your application, from low to high, to maintain operational efficiency in varied pressure conditions.
- Chemical and Abrasion Resistance: Depending on the type of fluids your application involves, check the materials of the pump in terms of chemical and abrasion resistance. The pump must be designed to transfer anything from pure fluids, slurries to semisolids.
- Adequate Capacity Storage: Opt for the pump with capacity storage that accommodates at least one complete cycle of your typical batch or operation volume, decreasing refill frequency and ensuring continuous operation without hindrance. Cannon Water Technology offers various capacity storage options, from 10 gph to 280 gph.
- Adjustability: An ideal pump should allow for easy adjustments in flow rate, typically achievable through changes in stroke length or speed, to adjust to changing process conditions.
- Safety Features: Select pumps with safety enhancements such as overpressure protection, leak detection, and diaphragm rupture indicators to protect your personnel and maintain system integrity.
Essential Installation and Maintenance Protocols for Industrial Systems
To ensure optimal performance and durability, various necessary regulations must be followed when choosing and installing industrial systems with mechanically actuated pumps.
- Pump selection: Consider factors like fluid viscosity and temperature to choose a pump with suitable capacity, pressure storage, and material compatibility required for a particular application.
- Installation location: The pump should be placed in an accessible location that is protected from mechanical damage, high ambient temperatures, and direct sunlight.
- Power supply: Provide a steady power supply for the pump and ensure proper grounding.
- Monitoring and control: Implement monitoring and control systems, like pulsation dampeners, to guarantee precise and reliable dosing.
- Preventative Maintenance: Clean the valves every 3 to 6 months and swap the diaphragm yearly.
- Suction and discharge lines: Keep the suction lines short and slant upwards to remove vapor pockets. Install a foot valve with a ball check valve, ceramic weight, and strainer for priming and shielding against coarse impurities.
- Safety: Follow the manufacturer’s safety guidelines.

FAQs for Mechanically Actuated Metering Pumps
- Can metering pumps handle high-viscosity fluids?
Yes, metering pumps can handle high-viscosity fluids, but choosing a pump designed for such applications is essential. Pumps with large inlet and outlet ports, powerful drive mechanisms, and specially designed diaphragms or pistons are better suited to moving viscous fluids effectively.
- What are the common issues with metering pumps, and how can I troubleshoot them?
Common issues include inconsistent flow rates, leaks, and blockages. Troubleshooting these problems typically involves:
- Checking for clogs in the line
- Ensuring the pump is adequately calibrated
- Inspecting for leaks in the pump head or fittings
- Verifying that the pump receives the correct power supply
- What is the recommended capacity storage for a metering pump?
The ideal capacity storage should accommodate at least one complete operational cycle, ensuring continuous function without frequent refills. When determining the capacity, consider process requirements, flow rate, and chemical stability.
- How do I maintain a metering pump?
Regular maintenance of a metering pump includes checking and cleaning the inlet and discharge valves, inspecting the diaphragm or piston for wear and tear, ensuring the motor and drive mechanisms are functioning correctly, and replacing any worn or damaged parts. It's also important to regularly calibrate the pump to maintain accuracy.
