Overview

This document presents detailed specifications and performance data for TACMINA's V Series motor-driven metering pumps, designed primarily for chemical injection applications. These pumps are engineered to handle a variety of chemicals including polymers, sodium hypochlorite, caustic soda, acidic chemicals, and boiler treatment solutions.

Product Line and Applications

• Polymer Pumps (VTSE/VTSF): Suitable for polymer coagulants with viscosities up to 2,000 mPa·s.
• Sodium Hypochlorite Pumps (ATCF): Equipped with anti-gas locking features to prevent operational issues.
• Caustic Soda Pumps (VTCE/STST): Designed for caustic soda and similar chemicals.
• Acidic Chemical Pumps (VTCF/FTCT): Suitable for sulfuric acid, hydrochloric acid, PAC, aluminum sulfate, etc.
• Boiler Chemical Pumps (VTCET): Intended for boiler cleaning and pH adjustment with high-pressure injection capability.

Key Features

• Chemical Injection System: Integrates a high-performance pump with compact tanks (30, 50, or 120 L) to improve usability and safety.
• Timer Control Compatibility: Supports timer control functions for flexible operation.
• Flow Rate Adjustment: Large, easy-to-read dial on top enables intuitive flow control.
• Pressure Relief Valve: Built-in simple relief valve automatically releases pressure during abnormal conditions to protect the system.
• Durability and Warranty: IP65 rated enclosure ensures dust and rain resistance; 3-year warranty under specified conditions, triple the duration of conventional models.

Technical Specifications

Dimensions and Connections

Models feature hose (HW) or flange (FW) connections with detailed external dimensions provided. Hose diameters and connection types vary by model. Some models include relief valves and cable ties; others do not.

Materials

• Pump heads and liquid-contact parts use materials such as PVC, PVDF, SUS304 stainless steel, PMMA, and PTFE, selected for chemical compatibility.
• Diaphragms, check balls, O-rings, and valve seats are made from ceramic, EPDM, fluoro rubber, and special fluoro rubber to ensure corrosion resistance and durability.

Performance Parameters

• Discharge volumes range from approximately 0.2 mL/min to over 21 L/h depending on model and operating frequency (50/60 Hz).
• Maximum discharge pressures reach up to 1.5 MPa (15 bar) for some models.
• Stroke speeds vary between 60 and 2000 strokes per minute; maximum stroke lengths are model-specific.
• Polymer pumps support liquid viscosities up to 2,000 mPa·s.
• Operating ambient temperatures generally range from 0 to 40 °C (no freezing), with some models rated up to 60 °C.

Power Supply and Electrical Specifications

• Power supply options include single-phase and three-phase configurations with voltages from 100V to 440V, supporting both 50 Hz and 60 Hz frequencies.
• Power consumption ranges from 0.23 W to 23.6 W depending on the model.

Installation and Accessories

• Accessories include pump securing bolts (M5 × 30), washers, flange nuts, various hoses (PVC braided, FEP, PTFE, PA tubes), anti-siphon check valves, foot valves, and ceramic weights depending on the model.
• Installation notes emphasize correct ambient conditions, proper drainage, and adherence to temperature limits to maintain IP65 rating and warranty validity.

Recommendations and Limitations

• Corrosion resistance depends on chemical concentration, temperature, and UV exposure; consultation with TACMINA is recommended for material selection.
• Simple relief valves are not included in larger models (600 and 1000) and certain types (STST).
• Flange connections are unavailable for FTCT and STST models.
• Warranty coverage applies only under specified operating conditions.

Technical Dimensions and Connection Details

Detailed external dimensions (in millimeters) are provided for various models including 00R, 300/300R, 600, 1000, and VTCE/VTCF series with flange connections. Key dimension parameters (A through G) specify length, width, height, and flange base positioning. Notably, flange bases are positioned lower than the installation surface for certain models, which is critical for proper installation.

Connection details specify hose and tube diameters, with notes on included or excluded components such as relief valves and flange connections. Compatible hoses include PVC braided hoses (1m and 3m), FEP, PTFE, PA tubes, and soft PVC hoses. Some models include anti-siphon check valves, foot valves, and relief/air release hoses.

Summary of Critical Parameters and Best Practices

• Model dimensions must be matched carefully to installation requirements.
• Flange base positioning is essential for correct installation, especially for VTCE/VTCF models.
• Hose and tube compatibility varies by model; selecting the correct hose type and length is necessary.
• Some models include relief valves and cable ties; these should be accounted for during assembly.
• Use specified securing bolts and washers to ensure stable and safe pump installation.
• Consult operation manuals and performance tables for detailed installation and operational guidance.

Summary

The TACMINA V Series metering pumps provide a versatile, durable, and user-friendly solution for precise chemical injection across diverse industrial applications. Their robust construction, advanced features such as pressure relief and easy flow adjustment, and extended warranty with IP65 rating ensure reliable and safe handling of corrosive and viscous fluids in demanding environments.
