Metering Pump > Pzi

BPL - Direct driven type - TACMINA Corporation
PZi Series

Popular PZ Series with
Intelligent Brain Now Mounted!!

When the next input signal is entered to a PZi pump during the operation in the multiplication mode, the number of pumping action after operation will be added (max. 9999 times).

<Applications>
  • Chlorine sterilization for small-scale water-supply system,food plants, buildings and swiming pools
  • Injection of chemicals to boilers
  • Chemical injection in the fleld of physics and chemistry plus medical cure
  • Very low flow rate at a high pressure injection of various other liquids

Ο Analog signal input

    [PZi4][PZi8] DC4 (0) to 20mA input
(1) Proportional band function
  (A) Pump can operate at 100% even if
the input signal is not 100% (20mA).
  (B) Pump does not operate at full capacity
even if the input signal is 100% (20mA).
(2) Shift function
  (A) Pump discharges the minimum amount
even if the input signal is 0 (4mA).
  (B) Pump does not start injection
until the input exceeds a certain value.

Ο Pulse signal input

(1) Frequency-division (1/1 to 1/9999 adjustable) [PZi4][PZi8]
 
(2) Multiplication (1 to 9999 adjustable)
 

Ο Stop-signal input

  [PZi4][PZi8]

ex.Level switch control

When the tank is empty:
  • The pump stops [PZi4]
  • The pump stops [PZi8]
  • The alarm indication works.
  • Alarm Signal is outputted.

Ο Pulse signal input

(1) Counter (Metering batch injection) [PZi8]
  Pump operates up to max.9999 × 1000 times by the start(switch)signal.
Multiplication setting.(Such as × 1, × 10, × 100 and × 1000.)is available.
Type 31 discharges up to max. 0.99 × 1000. L by one signal. (Indication counts down.)
(2) Interval function  
  ON time and OFF interval can be freely set
from 1 to 9999 min. respectively.
(Operation repeats this setting.)
