Connecting Suction Piping; Discharge Piping; Air Piping; Preparation For Use - YAMADA 40 Series Instruction

3.5 Connecting suction piping

As the pump start operation, the shovel in the suction port starts
reciprocating. Do not place any piping equipment in the operating range
of the shovel.
Refer to Fig. 7 for the operating range of the shovel and mounting
dimension for piping.
Apply leak prevention, putting a gasket, for example, to the connection
between the flange section of the material inlet of the pump and piping.

3.6 Discharge piping

1） Connect a discharge hose to the pump outlet. Make sure the hose satisfies the following requirements:
- Resistant to material being pumped and unaffected by environment
- Satisfying the following normal operation pressure:
-13×1 ratio pump: 10MPa or more
-25×1 ratio pump: 18MPa or more
-38×1 ratio pump: 27MPa or more
-50×1 ratio pump: 35MPa or more
- Recommended size: 3/4 inch or more
- When mounting the pump on an elevating machine like a lift, be sure to use a flexible hose with an adequate
length in order not to be affected by up-and-down movement.
- Hose fitting or joint: <140 Type>Connectable to G3/4(F) material outlet, hose union with a 30 degree male seat
2） Connect the other end of the hose to a delivery pipeline. Attach a valve at the connection between the hose and
the piping for maintenance and keep it closed until unit installation is completed.

3.7 Air piping

1） Connect air piping equipment such as an air valve and air regulator to the air inlet of the pump. Attach an
emergency stop valve to the air pipe (somewhere accessible between the air source and unit).
2） Select an air supply hose, fitting, and air equipment that satisfy the following requirements. With these devices,
connect an air piping and the air inlet of the lift. Be careful not to let the hose get caught on peripheral
equipment.
- Designed for use with air and unaffected by environment
- Normal operation pressure: 0.7MPa or more
- Recommended size: 3/8 inch or more
- Hose fitting or joint: Connectable to Rc3/8 air inlet
- Comfortable hose length for up/down movement of the lift
- Flow rate: 1300L/min (ANR) or more
<NOTE>
The air regulator controls supply air pressure to the pump. Accordingly, the pump operates efficiently without
unnecessary movement and thus the life of the pump can be extended.

3.8 Preparation for use

The pump has been tested using mineral oil before delivery. Please wash inside the pump with appropriate solvent
for the material being pumped.
