This is a pressure-resistant explosion-proof type electromagnetic-driven metering pump that enables use in explosion-proof areas.
It supports external pulse control and external analog signal (4 to 20mA DC) control, and is suitable for various processes including the gas and chemical industries.

Pressure-resistant explosion-proof structure: Obtained explosion-proof certification from the Industrial Safety Technology Association
(Certification number: TC18339 Explosion-proof grade and ignition degree: ExdⅡCT6)

● Chemical injection in explosion-proof areas
Injection of odorant into gas pipes
Injection of pH adjuster
Injection of disinfectants such as hypochlorite
● Micro-quantitative Injection of volatile chemicals (ethanol, IPA, etc.)
● Research, development, and prototype facilities (micro chemical injection)

Discharge rate：0.027 – 1,000 mL/min
Discharge pressure：0.15 – 2.5 MPa
Discharge reproduction accuracy: ±2% (standard model’s liquid-end parts, under conditions recommended by the manufacturer)

Power supply specifications：Single-phase 100/200 VAC　50/60Hz

Liquid-end parts

＜Air extract valve＞
Manual air extract valve: Turn the knob by hand to release the air in the liquid part.
Automatic air extract valve: Automatically and continuously release the air from the liquid-end parts.

＜Connection diameter (depending on the material of the liquid-end parts)＞
Compatible with many hose diameters (4 x 6, 9 x 12, etc.), and can be connected to pipes and flanges.

＜Diaphragm damage detection function＞
Equipped with 2501SSM and 2051SBM to prevent troubles caused by the chemicals due to diaphragm damage.

Drive part

＜External signal operation＞
Pulse signal operation: The number of strokes is controlled by a non-voltage pulse signal. (1 pulse = 1 stroke)
Analog signal operation: The number of strokes is proportionally controlled by an analog signal (0/4 to 20mA).
Remote On / Off operation: The pump starts or stops with a contact signal without voltage.

＜Structure suitable for outdoor use＞
Compliant with IEC standard IP65 (suitable for outdoor use)
IP = Ingress Protection
IP6* : Complete dust-tight protection: A structure that prevents dust from entering inside
IP*5 : Protection against water jets: A structure that is not adversely affected by jets from any direction
