System Components
The SWPS system consists of two parts, one of which comes packaged in an optional weatherproof NEMA 3
rated case. The case is opened by unsnapping its eight latches and lifting off the top with its two handles. Held
in the top of the case is the input hose assembly.
A 20’ (6 m) output hose is also included.
There is portal access on each side of the optional case. Looking down on the system, the PCM appears as in
Figure 1-1, the portal on the right permits access of the input hose and the cables from the Product and
Tankfull probes. The left portal is for the output hose and power cord.
Pump Control Module (PCM)
The PCM is designed for rugged use either with the probe or as a portable transfer pump and is explosion
proof (EP) and Intrinsically Safe (IS) for Class 1, Division 1, Group D hazardous locations. The PCM contains
several sub-assemblies which are described as follows.
Explosion Proof (EP) Control Switch Box
The EP control switch box houses the ON/OFF switch, the HAND-OFF-AUTO control switch, and an alarm
indicator. The box also contains the receptacle connection for the probe and Tankfull cables, various control
relays and the fuse blocks.
Pump/Motor
The motor (1/4HP, 1725 rpm) is explosion proof and has thermal overload protection. A self priming gear pump
is attached to the motor with a three part, flexible coupling. This motor is used in both the 115V and 230V
models and is factory wired for the correct voltage and rotation.
Pump
The pump is a Viking 4 gpm (17 lpm) hydraulic pump with carbon bearings and Viton seals. The pump is
mated to the motor with a spider coupling. 1/4-20 socket set screws make the shaft to shaft connection. Some
non-detergent oil should be squirted into the pump occasionally, especially if it has been pumping gasoline or
solvents or if it is going into storage. Water left in the pump will cause damage.
Alarm Indicator
This red indicator signals either a Tankfull condition or the presence of water within the well. During a Tankfull
condition, the indicator will remain illuminated with the control switch in the OFF position. During a water alarm
condition, the indicator will go out when the control switch is turned to OFF.
Weatherproof Connectors
These ports contain Intrinsically Safe wiring and provide receptacles for the Tankfull and probe control
connectors.
Alterations to the output hose length may be necessary to accommodate the distance
between the motor/pump depth and the PCM and recovery tank location. Consult with
Geotech on unit specifications.
