5 Pump –general
5.1 Preparation for starting the pump unit
The PT series pumps are self-priming piston pumps with leather piston cups. When the piston cups are
wet they expand against the cylinder sleeve so that the pump can build up vacuum. Therefore the pump
housing must be filled with water.
5.2 To fill the pump housing with water:
1. Remove the upper cover (1) from the stone catcher.
2. Fill the stone catcher with water.
3. Close the cover.
5.3 Control panel
− PT250 pump is supplied with a star-delta switch(4). Switch has three positions: Neutral (1), Star (2)
and Delta (3).
− Connection socket 32A (5)

12
5.4 Checking the direction of rotation
WARNING
This test may only be performed by authorised personnel with the appropriate
training.
Check whether the direction of rotation of the motor matches that of the pump.
To check the direction of rotation the motor must be switched on briefly. The motor must not be allowed
to reach the normal operating speed.
If the direction of rotation is incorrect, the connection on the terminal board must be changed or, if a
phase reversal plug is present, the pins of the plug must be reversed.

13
6 Daily maintenance of the pump
− Check the oil level of the pump.
Note
If the oil in the pump drive has become whitish in colour, replace the oil. The whitish colour may
indicate the presence of excessive condensation water in the oil.
− Check for possible leaks in the oil and fuelhoses.
− Check the dripping of the gland packing on
the piston rod; this should not exceed one
drop every five seconds. It may be necessary
to readjust the gland packing at greater lift
heights.
− Check that the dripping water can drain away from the gland packing. The channel must notbe
plugged on the outside by dirt and sand that have splashed onto the enclosure.
− Check whether the machine is still placed properly on the ground on which it stands, in accordance
with the instructions. This is important, because the situationcan change as aresult of a build-upof
sand/soil around the pump unit.
− Check the vacuum above and below the filter in the stone catcher using the two vacuum
gauges on the stone catcher. A difference between the two readings indicates restriction of
the filter, in which case it must be cleaned.
− Clean stone catcher in following steps
1. Open top cover of stone catcher unscrewing two 24mm nuts, carefully take off cower (1).
2. Look inside, if dirty clean out all obstacles.
3. Place back cover and tighten it up.

14
7 Preperation for starting
1. Take any necessary measures to ensure that the electrical connections and cables cannotbe damaged
2. The voltage and frequency must be checked in advance and must match the motor specifications. This
data is shown on the type plate of the motor.
3. Use of the motor without an overload protection switch is not permitted
4. Check whether the motor connection matches the mains voltage. See the type plate for the motor. Check
the connections in the terminal box behind the control panel
5. Check the direction of rotation of the pump
6. Check the oil level in the drive unit (1).

15
8 Starting and stopping
1. To start the pump, make shore main switch is on “0” position (1) the switch must first be turned to
the star (2) position, and then turned to the delta (3) position within one second.
2. switch must first be turned to the star (2) position for about 1 second.
3. And then turned to the delta (3) position within one second.
WARNING
Turning theswitch too slowlywillcause themotor's thermal protection totrip.Return the
switch to the neutral position and switch it on again.

16
Stopping
To stop the motor, the switch must first be turned from Delta (3) position to the star (2) position,
and then turned to the neutral position (1) within one second.
− When you suspect that the liquid is beginning to freeze, drain the pump while the medium is still in the
liquid state.

17
9 Regulating vacuum on suction line
If it is necessary to reduce the vacuum on the header pipe somewhat, this can be accomplished by slightly
readjusting the blow valve (1) on the pump. This results in a bit of air leakage developing in the pump at the stone
catcher, which will slightly reduce the total vacuum on the header pipe.
Unscrewing the nipple increases the bleed air from the vacuum regulator valve.

18
10 Monitoring during operation
1. During operation check the pump regularly for correct functioning, smooth and vibration-free running
abnormal noises and leaks.
2. If the pump has pumped for a long time without having moved water, the pump housing must be filled with
water, because the cups shrink after having run dry for a long time. Once the pump housing is filled with
water, the cups will slowly swell again so they are in contact with the cylinder.
3. Check whether the gland packing is leaking; it must be adjusted so one drop of water drips every five
seconds. Loosen the gland packing a bit if it drips more slowly and tighten it a bit if it drips more quickly.
4. The maximum permissible ambient temperature is 40 °C. The temperature of the bearings may not exceed
110 °C.
Note Use for higher temperatures is only permitted after consultation with the supplier.
WARNING
In the event of a problem or incorrect functioning, stop the pump. Determine and
correct the cause before restarting the pump.
