4.1.4 Pump Fixation (Option)
The pumps are provided with casters for easy transportation and foot
adjustments for anchoring and height adjusting, as described in Section 4.1.2.
The pump, however, may unexpectedly move or fall down when an earthquake
occurs. To prevent such events, EV-S dry pumps (CE/SEMI compliant) are
equipped with brackets to secure the pump body to the floor. Fix the pump to
the floor or other firm ground with the brackets at the installation.
For dimensions of the bracket, see the accompanying drawing.
Anchor bolts should be fit for conditions of the floor where the pump is
anchored.
WARNING In MODEL EV-S20 type pump, the bolt which is fixing the fixing
bracket to a pump is M6✕16. This fixing bracket can use as
lifting-bracket.
When you use this bracket as lifting bracket, you use M6✕12 bolts
for fixing this bracket to the upper side of the pump. In this case,
you cannot use the M6✕16 bolts, because the M6✕16 bolts reach
to an internal part and have a possibility to break it.
・Using this bracket as a fixing bracket, please use the bolt of
M6✕16(hexagon head bolts).
・Using this bracket as a lifting bracket, please use the bolt of
M6✕12(hexagon head bolts).
