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).

Note:
- Discharge volume
values are for reference
only, and may differ
slightly according
to individual site
conditions and product
differences. (conditions:
room temperature,
clean water, suction
height -1.5 m)
- Max. discharge viscosity
is 50 mPa•s.
- The solenoid is
not explosion-proof.
Take sufficient not
of this when selecting
the model.
- These values are
for liquid-end material
types FEC, FFC, VEC,
VFC and CL. Contact
your supplying agent
separately for other
materials.
- Hose is provided
in the case of FEC/FFC
(CL on ARPZi) type.

Notes:
- Special fluoro-rubber,
or Vyton by trade
name, is a copolymer
of vinylidene fluoride
and propylene hexafluoride.
It is approved by
The Food Sanitation
Test by Ordinance
434 of the Ministry
of Health and Welfare
of Japan.
- EPDM is a copolymer
of ethylene, propylene,
and diene compounds,
and is approved by
The Food Sanitation
Test by Ordinance
434 of the Ministry
of Health and Welfare
of Japan.
- PVDF (polyvinylidene
fluoride) is a di-fluoride
resin, and is approved
by The Food Sanitation
Test by Ordinance
434 of the Ministry
of Health and Welfare
of Japan.
- PTFE (tetrafluoroethylene
resin), or Teflon
by trade name, is
a type of fluoride
resin.
- The 6TC, STC and
FTC types are custom
order products.

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). |

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. |
