Comet MTP LW-K 13/170 TS VA [40/104] Hydraulic connection

• e motor pump must operate without exceeding the pressure limits as shown on the plate (12). In particular,

always make sure the pressure limiting/unloader valve is correctly set and that this setting is guaranteed, e.g.,

by paint coating.

e pump applications must be made following good mechanical engineering practices. e Manufacturer’s

Aer-Sales Service is at the disposal of the

Skilled Technician

to provide all necessary information.

HYDRAULIC CONNECTION

For the hydraulic suction, delivery and bypass connections, refer to the following table and to Fig.16, which

represents a generic diagram of a possible machine integrating the motor pump.

A. Pump

B. Pressure limiting/unloader valve

C. Suction circuit

D. Delivery circuit

E. Lance (example of accessory)

F. Engine

CAUTION

• Follow the connection instructions already indicated in the

“ChECkING AND CONNECTING UP TO ThE WATER

SUPPLY”

and

“SPECIFICATIONS AND TEChNICAL DATA”

paragraphs.

In particular, the suction circuit must be sized so as not to determine on the motor pump suction tting:

- a pressure higher than 8bar/116psi;

- a vacuum higher than 0 bar/0 psi (

MTP KTR - MTP KTR Misting - MTP KMR - MTP KSR - MTP KSR Misting- MTP

AX Misting - MTP LW Misting

); 0,05bar/7,25psi (

MTP LWR-K 250 - MTP LWR-K - MTP ZWR-K - MTP AXR

);

1bar/14,5psi (remaining motor pumps).

• At motor pump suction, a lter of adequate dimensions must be tted. In case of doubts, contact the

Manufacturer.

• e suction pipes must have a suitable internal diameter and a nominal pressure of 10bar/145psi.

• e delivery pipes must have a nominal pressure not below the motor pump max. pressure.

• Do not supply the motor pump with liquids at a temperature above 60°C/140°F (50°C/122°F for MTPKTR,

MTP KTR Misting, MTP KMR, MTP KSR, MTP KSR Misting) or below 5°C/41°F.
