2. Product introducon
H series pumps are mulstage stainless-steel pumps with
closed impeller and for high pressure applicaons. Pumps
can reach pressure up to 25 Bar thanks to mulstage pump
construcon. When the pumps work as serial it possible to
reach higher pressure up to 50 Bar.
The main applicaons of the high pressure pumps;
 CNC lathes,
 CNC machining centers,
 Especially deep hole boring operaons,
 Erosion machines,
 Washing processes,
 Cooling systems.
High pressure pumps have stainless steel (AISI 304) impel-
lers and diusers which have a good chemical resistance
against to various chemical liquids. There are O-rings be-
tween diusers and impellers to reach high pressure and
prevent back ow to have high eciency. O-rings are made
of Viton for high chemical resistance.
Mechanical Seal
Mechanical seals are consist of four parts. These parts are;
stable part, rotary part, bellows and spring. Mechanical seal
materials must be choose according to liquid specicaons
and pump applicaon type. These materials are shown the
table below.

If H series pumps will be used on grinding applicaons or
ltraon systems for pumping highly contaminated liquids,
TC mechanical seals must be chosen due to the good me-
chanical resistance against to metal chips or abrasives. All
the O-rings will be removed for these applicaons. Because
abrasive metal dusts can damage to O-rings which will re-
sult the failure of the pump.

tained in this manual, the relevant naonal accident pre-
venon regulaons and any other service and safety in-
strucons issued by the plant operator are to be observed.
 During Operaon
If hot/cold machine components involve hazards, they
must be prevented against accidental contact.
Guards for the moving parts (e.g. coupling, fan) must
not be removed while the pump is running. Also make
sure that guards are never in contact with the moving
parts by using proper protecon parts
Any leakage of hazardous (e.g. explosive, toxic, hot)
uids must be drained away to prevent any risk to sur-
roundings.
Always close the terminal box to prevent hazards
caused by electricity.
5.1 Before installaon
 Check the nameplate and performance curve to ensure
that the pump meets requirements of your applicaon
(Delivery head, ow rate, viscosity etc.).
Make sure that the product operates within its working
range. Only then the product performance is guaran-
teed.
Check the condion of the pump for any damage that may
have occurred during shipping.
Keep the pump vercal and prevent from falling down.
The electrical supply should be veried so the voltage,
phase and frequency match that of the pump motor.

5.2 Mechanical installaon
Place and install the pump on a at surface on the top of
the coolant tank with the pump body being immersed in the
coolant. Immersion depth of the pump should be at least 25
mm shorter than the depth of the tank and minimum uid
level should exceed lower stage of the pump.
The piping must be fully installed and bore diameter have
to be chosen according to the discharge of the pump. Flow
rate can be adjusted by installing a valve on the piping and
on the delivery connecon of the pump. Be sure that piping
is capable of delivering the hydraulic pressure.
Check the pump stayed out of use for a long me by turning
the sha via hand before installaon. Make sure that the
sucon of the pump is not clogged.
Do not block the air ow through the motor. Make sure
that sucient air can pass the cooling fan.
Check the direcon of rotaon of the pump and designated
direcon on the label on the top of the pump before start
up.
6.1 Start-up
Install the pump according to ‘Installaon’ heading in the
manual.
Switch o the mains and connect the terminals according to
‘Electrical connecons’ heading in the manual. Then close
the terminal box.
Check installaon and electrical connecons steps one
more me before starng up the pump.
Briey start the motor to check the direcon of rotaon
according to the arrow on the top of the motor (By looking
through the fan cover that has to turn clockwise for H series
pumps). For three-phases motor, interchange two of the
power leads if the direcon is incorrect.
Make sure that the temperature of the medium is inside of
the designated limits of the pump.

scribed in the nameplate of the pump.
5.3 Electrical connecons
Centrifugal pumps consist of air-cooled squirrel cage elec-
tric motor and pump parts. Pump is connected to the motor
perpendicularly via bolts, coupling etc. to operate inside the
liquid.
A faulty motor or wiring can cause electrical shock that
could be fatal, whether direct contact or conducted
through standing water. For this reason, proper ground-
ing of the motor frame to the power supply's grounding
terminal is required for safe installaon and operaon.
Only trained sta should make the electrical connec-
ons of the pump unit. Otherwise, electrical shocks can
cause fatal injuries.
 Before running the pump unit, be sure about the electri-
cal connecons and connecon type. Appropriate volt-
age level and connecon type are shown below.
 Ground terminal of the motor is inside the terminal box.
This terminal must be connected to the terminals of the
Networks ground terminals.
 Bolts of the connecon cables must be ghtened. Loose
connecons cause overheat and faults of the motor.
 Before run the pump, all the mechanical and electrical
connecons of the pump has been made. Check all of
the bolts are fastened ghtly.
 Use appropriate fuse and thermal switches etc. to pro-
tect the motor damages of the faults
 Always check the voltage level of the pump unit before
maintenance and before opening the terminal box.

8. Troubleshoong
Do NOT run H series pumps dry.
Check the allowed parcle size in the medium and pre-
vent the pump from bigger parcles.
Do not start HC-HD series horizontal pumps unl it has
been primed.
Priming (Only for HC and HD series pumps):
1. Close the valve on the discharge side of the pump.
2. Open the valve in the sucon pipe completely before
starng the pump.
3. Remove the priming plug shown in Figure below.
4. Fill the pump housing and the sucon pipe completely
with liquid unl a steady stream of liquid runs out of the
priming hole.
5. Fit and ghten the priming plug.
6. Slowly open the discharge isolang valve while the pump
is running. This ensures venng and pressure build-up dur-
ing start-up.
If the pump is not building up pressure, it may be nec-
essary to repeat steps 1 to 6.
