Picture of the BF pump with guide rail system
6.2.16 The Guide rail system consists of the following parts:
- footing
- 2x guide rail (not included in the shipment – provided by customer according to the necessary length)
- movable hook
- upper holder of guide rails
- stainless-steel chain of 4m length
6.2.17 Dimensions of discharge flanges series AL. BF, SS, SF, AF, GF and GRS are not in accordance with
Č
SN/DIN and therefore are equipped with thread counterflange or welding-neck counterflange.
6.2.18 During instalation GRS care about dimension of acces hole above the pump Y>X ! Otherwise is not possible to
take out pump from sump.
6.2.19 Fixe the footing to the sump bottom using anchor bolts embedded in concrete. The bolts and nuts must be
made of stainless steel. On the footing, there are two benches for seating the guide rails that are attached by
the upper holder up in the acces hole.
For the correct placement of pump on footing is necessary to install the footing in a horizontal position!
6.2.20 Upper holder of guide rails fixe near acces hole for pump (stainless steel anchor bolts or another construction).
If want to drill anchor bolts to concrete care about sufficient height (thickness) of roof. During installation it is
necessary to make sure that the guide rails are in vertical position.
6.2.21 If the guide rails are long must be fitted every 3 meters by side bracing (see picture above) as protection
against lateral deflection of guide rails. Furthermore it is necessary to anchor the discharge pipe in
consideration of its bending resistance.
6.2.22 Remove the base stand (three legs with round rubber pads) and the counter-flange and mount on the movable
hook (or hook with bend – depend on type). Let the pump go down in the reservoir using the guide rails. The
movable hook will automatically fit in the footing. It is possible to take the pump out for a revision or repair
without any need to dismount anything.
6.2.23 In case of 32GF21.0 with GRS T50E must be from oval flange of movable hook on pump side milled or ground
off about 3mm material. Otherwise can not be movable hook mounted on the pump. If GRS is not supplied
with this modification has to be made additionally.
6.2.24 The cables can not be slack under the pump as they could be sucked in the hydraulic area (We recommend to
attach the cable to the stainless steel rope or chain, on which you lower the pump down, cca every 2 m).
6.2.25 Before switch on the pump the sump must be cleaned of any abrasive and large dirt.
6.2.26 Before switch on the pump it is necessary to check whether the pump is properly seated on the footing before
the sump is filled in for the first time.
