The respect of the mounting instructions (2.1.1. Hydraulic, 2.1.2.
Fastening, 2.1.3. Electrical) brings a total security to the customer.
The following dielectric tests are applied to:
coils during the manufacture : 5000 volts for 2 seconds
assembled pumps type ET_ - EK_ : 3500 volts for 1second
assembled pumps type EM_ : 2500 volts for 1second
3.1. general precaution
The ET_ - EK_ - EM_ are devices made to pump liquids. Any other
kind of uses are prohibited.
The pumps generates warmth (45-60°C), which can hurt lightly. It is
recommended to mount the pump in a way to avoid any accidental
contacts.
The pump should not be hit. The plastic end fitting are breakable, the brass
and stainless steel end fittings might be crushed if the pump is dropped.
The coil body, black plastic part inserted in the metallic block, reaches an
average temperature of 45 to 60 °C under normal use. This heat must be
evacuated, so foresee space around the pump.
The pump weights 450 to 600 grams and must be handle with attention to
avoid injuries.
The pump vibrate at 50 or 60 (Hz). Cares must be taken to keep clear of
contact with other fastened parts.
The two electrical connections (plus & minus) must be protected against a
common metallic contact which will turn into a short circuit. It is recommended
to use plastic housing for the connectors to avoid any accidental contact with
electrical conducting materials.
3.2. Dry running
A long dry running will conduct to :
The melding of internal parts.
The stop of the piston movement.
The overheating of the coil.
