DESCRIPTION
K
Compressed air operated piston-type reciprocating pump. This high flow capacity pump is compatible with mineral and synthetic grease and suitable for
large installations with long lengths of piping supplying several outlets simultaneously. This pump is mounted directly on 44 lb, 110 lb and 408 lb (20 kg,
50 kg and 185 kg) drums.
WARNINGS
WARNING:
Read all instruction manuals, tags, and labels
before operating the equipment. This equipment is for
professional use only.
!
• The use of non compatible fluids may cause damage in the pump and
serious personal injury. This equipment is not intended for use with
fluids that fall within the Group 1 fluid as defined that are explosive,
extremely flammable, highly flammable, flammable, very toxic, toxic,
oxidizing or where the vapor pressure if greater than 7 psi (0,5 bar) above
the pressure atmospheric at the maximum allowable temperature.
• The pump generates high or very high pressures. Do not exceed the
maximum air inlet pressure of 145 psi (10 bar).
• A direct hit against the human body may result in an injury.
• This unit may have stored pressure, release all pressure and disconnect
from any fluid systems before servicing. To ensure safe operation of this
unit, all service work should be by qualified personnel only.
• When not in use, be sure to shut off the air supply to avoid accidents.
• Do not alter or modify this equipment. Use only Samoa Industrial, S.A.
genuine components. Any unauthorized tampering with this equipment,
improper use, poor maintenance or removal of identification labels may
invalidate the guarantee.
• All fittings in the system connected to the outlet of the pump should be
suitable for the maximum possible pressure generated by the pump/air
motor. If the systems cannot be designed to take the maximum pressure
produced by the pump, safety valves or diverter valves should be fitted.
It is recommended to install this pump on a drum using the bundled bung
adapter with a suitable drum cover for 407 lb (185 kg) drum, for 110 lb (50
kg) drum and for 44 lb (20 kg) drum). Fasten the cover onto the drum
and screw the nut of the bung adaptor securely into the 2" bung
opening of the cover. Insert the pump through the nut and adjust it with
the star nut to the desired height (see Fig. 2).
It is also possible mounting the pump directly fastened on a flat surface,
using the 4 threaded holes (M8) disposed in a
∅3.54” (90 mm)
pattern
in the fluid outlet body.
INSTALLATION
Figure 3 is a typical installation shown with all the recommended
accessories for the pump to operate correctly.
NOTE:
The compressed air supply must be set between 29 and 145 psi
(2 and 10 bar), being 90 psi (6 bar) the recommended pressure. An air
closing valve must be installed, in order to be able to close the compressed
air line at the end of the day (If the air inlet not is closed and there is a
leakage in some point of the grease outlet circuit, the pump will start
automatically, emptying the container).
