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

Note:
- Conditions: Clean water, room temperature
- Though the max. discharge pressure of the 30R models is 1.0 MPa, the Relief Valve operates when 0.7 MPa is exceeded. In applications requiring a discharge pressure of 0.7 MPa or more, ask for a model w/out the Relief Valve, and install a separate relief valve for extra safety.
- Though the max. discharte pressure of the 60R models is 0.8 MPa, the Relief Valve operates when 0.7 MPa is exceeded. In applications requiring a discharge pressure of 0.7 MPa or more, ask for a model w/out the Relief Valve, and install a separate relief valve for extra safety.
- Combined use of Analog-Input signal and high-speed pulse signal not possible.

[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) |

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.) |
