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)>
● Main liquid-end parts: PVDF
High corrosion resistance resin PVDF (polyvinylidene difluoride) is adopted to main liquid-end parts which is high resistance against not only general chemicals but also acids and alkalis.
● 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 chemicals from which bubbles tend to be generated.
● 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) operation mode
Pump stroke frequency can be controlled automatically by interlocking with external pulse signal in combination with pulse generating flowmeter etc.
One (1) pump stroke with one (1) pulse signal (synchronous) in normal setting. Multiplying and Dividing modes are also available.
Multiplying setting:
When pump stroke frequency is increased against pulse input numbers.
Memory function to store input pulse signals to pump operating (ON/OFF setting available)
Dividing setting:
When pump stroke frequency is decreased against pulse input numbers.
Memory function to store input pulse signals to pump operating (ON/OFF setting available)
※Setting range of input pulse numbers (n: 0.01 to 99.99)

●Analogue input operation mode
Proportional control of stroke frequency in interlocking with analogue signal (0/4 to 20mA) from outside.

● For injection chemical for water treatment agents, acids and alkalis
● For chemical injection in physics and chemistry and medical fields
● For small water-supply system and chlorine sterilization for swimming pools
● For boiler chemicals
● For nutrient and disinfectant for hydroponics and stock-raising sites
