1. Before installation
1. Do not run pump dry (except for the start-up dry
running to fill the pump head with liquid.)
Friction heat builds up in the pump head during
dry running and the plunger seizes in the cylin-
der.
2. Do not close valves
Closed-discharge operation causes a sharp
pressure rise and may result in pump failure or
motor burning out. Be sure to open a suction line
and a discharge line before operation.
3. Degassing
Fully open a discharge line and set the pump
head angle to 20
º
(the maximum stroke length).
Run the pump in this condition to expel air from
the pump and tubing.
4. Temperature influence
A flow rate, liquid viscosity, vapour pressure and
corrosion resistance changes with liquid tem-
perature.
CAUTION:
The allowable liquid temperature range is
0-80ºC. Apply heat-resistant grease to the
motor bearing or use a cooling fan to cool
down motor temperature when liquid tem-
perature exceeds 65ºC.
5. Viscous liquid
The pump is capable of handling liquid up to
20,000 cP, but then keep pump rotation speed
lower as viscosity gets higher, especially when
liquid viscosity is 500 cP or more. Contact us for
detail.
