A pressure-resistant explosion-proof electromagnetically driven metering pump that can be used 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 by the Industrial Safety Technology Association
(Certification number: TC18339 Explosion-proof grade and ignition degree: ExdⅡCT6)

● Grout in explosion-proof areas
Injecting odorant into gas pipes
Injection of pH regulator
Injection of hypochlorite fungicide
● Injecting a small amount of volatile chemicals (ethanol, IPA, etc.)
● Research / development and trial production equipment (trace drug injection)

Discharge rate：0.027 – 1,000 mL/min
Discharge pressure：0.15 – 2.5 MPa
Discharge reproduction accuracy：±2% (Standard wetted parts, conditions recommended by the manufacturer)

Power supply specifications：Single-phase 100/200 VAC　50/60Hz
* Overseas power supply specifications are also available, please contact us.

Wetting part

＜Air bleeding valve＞
Manual air bleeding valve: Turn the knob by hand to bleed the air in the liquid part.
Automatic air bleeding valve: Automatically _and continuously bleeds air in the wetted parts.

＜Connection diameter (depending on the quality of the wetted 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 from 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 is started _or stopped by a non-voltage contact signal.

＜Outdoor usable structure＞
Conforms to IEC standard IP65 (can be used outdoors) IP = International Protection
6: Perfect dustproof shape: Structure that prevents dust from entering inside
5: Jet-proof type: Structure that is not adversely affected by jets from any direction
