Overview: Showa
DPB, DSA piston distributor systems deliver small doses of oil to
-
multiple points on many
types of machinery. In order to function these systems need a
-
lubricator with a timer,
a network of tubing and hoses, and piston distributors.

Lubricators: Showa
lubricators which operate piston distributors are usually 100-110v,
-
or 200-220v. Pressure range
from 12 kg/cm2 (172 psi) to 15 kg/cm2 (215 psi) on
-
systems which are operating
properly. Timers are built into some lubricators and others
-
use the controls on the
machine as their timers. Some type of timer must be used for the
-
system to function. All
lubricators contain a pump and motor. All pumps used in these
-
systems are continuous
gear pumps which also contain depressurizing mechanisms. Piston
-
distributor lubricators
must have depressurizing mechanisms to function properly. Other
-
accessories found on these
units are pressure switches, float switches, instant feed buttons
-
and pressure gauges. Lubricators
have part numbers starting with LCA & LCB followed
-
by a series of numbers.
Older units have numbers like MLA03W. Pump and motor units
-
which are used on these
units have numbers like MLA & MLB followed by two numerical
-
digits and a W.

Piston Distributors:
DPB, DSA piston Distributors are the most common showa piston
-
distributors you will find
on machinery. They come with different outlets and thread
-
sizes. Dosage Nipples are
attached to the outlet of the piston distributor which determines
-
the outlet volume of oil.
Example, 0.1cc or 1.0cc are just two different flow outputs that
-
can be selected.
