Common
<Applicable for high discharge pressure > (MP-L30P/N)
Max. discharge pressure is 1.6MPa. It enables a continuous injection to injection point at 1.0MPa of back pressure.
<Compatible with various control signals >
It is compatible with “contact signal (pulse) input” and “analog signal (0/4~20mA) input” to enable automatic operation mode, and various operation modes with remote ON/OFF, batch operation and special operation function.
* Optional control cable is necessary.
Standard type / Non-gas lock type
<MP-L30/60/200P (Standard type)>
Adoption of Highly Corrosion-Resistant Resin (PVDF) Heads
Highly functional resin PVDF (polyvinylidene fluoride), which is resistant not only to general chemical solutions but also to acids and alkalis, is used for the pump head and fittings.
Manual air extract function is standard equipment
Air in liquid-end parts is easily extracted by rotating the air extract valve even while pump operation.
<MP-L30/60N (Non-gas lock type)>
The most suitable for injection of bubble generating chemicals such as Sodium hypochlorite, etc.
Reliable air extract function
Quantitative injection without gas lock by air extract function in liquid-end parts working automatically even for chemical liquids prone to bubble formation.
Acrylic pump head: liquid moving in the pump head is visible
Generation of the gas lock (air lock) and discharge status can be checked from outside.

Three control operation functions

Manual operation mode
Select ON/OFF and stroke frequency (0 to 180spm) on the operation panel of pump body. By means of control cable, it is externally operatable by ON/OFF signal from outside without pump power off. (Remote ON/OFF function)

Digital Input (Pulse) Mode
Function: Automatically controls pump stroke count via external pulse signals (e.g., pulse-output flow meters).
Operation Modes (n=0.01 to 99.99):
Synchronized: 1 input pulse = 1 stroke.
Multiplication (1:n): Increases strokes relative to inputs.
Division (n:1): Decreases strokes relative to inputs.
Memory Function: Stores incoming pulse signals during operation (ON/OFF selectable).

Analogue input operation mode
The number of strokes is proportionally controlled in response to an external analog signal (0/4–20 mA).

Used to inject various chemical solutions such as water treatment chemicals, acidic agents, and alkaline solutions.
For chemical injection in physical and chemical sciences, and medical field
Designed for chlorine disinfection in small-scale water supply systems and swimming pools.
For injection of boiler chemicals
Suitable for injecting nutrient solutions and disinfectants across hydroponic farms and livestock barns.
