4.2 Horizontal Pumps
4.2.1 Installation
Horizontal magnetic drive & seal pumps are very sensitive to suction conditions. Often pump problems are caused by poor suction
conditions. The bigger the pump and the higher the temperature, the more important the general hydraulic guidelines should be applied.
Always try to respect the basic rules for liquid velocity v (m/s) and NPSH.
We recommend for Suction side v = 1 - 2 m/s; Discharge side v = 1,5 - 3 m/s
Flow (l/h) Inner pipe diameter (mm)
15 20 25 32 40 50 65 80 100
Velocity (m/s) at given ow (l/h)

8000 4,53 2,76 1,77 1,13
10000 5,66 3,46 2,21 1,42 0,84
15000 5,18 3,32 2,12 1,26 0,83

40000 8,85 5,66 3,35 2,21 1,4
Golden rules for proper pipe work
1. Keep suction pipe as short as possible.
2. Increase pipe size on suction side by at least one pipe diameter for longer suction pipe and/or higher temperature.
3. Use eccentric adaptors at varying diameters to prevent air pockets.
4. Avoid elbows, bends and ttings at suction side. When unavoidable keep ttings at a distance of 10 times pipe diameter away
from pump inlet.
5. Pipe work should slope up towards pump to prevent air pockets.
6. Pipe work should be completely leak free.
7. Support pipe work near to pump to prevent stress on plumbing.
8. Allow sufcient liquid level to prevent air intake on suction side.
9. Use generously oversized strainer in case of foreign particles.
10. Use siphon breaker when priming over top of tank.
11. Never throttle pump on suction side.
12. In case of doubt consult Hendor for proper sizing and NPSH calculation.
4.2.2 Operation and maintenance
Magnetic drive pumps. How it works?
Driver (motor) and impeller (driven) are physically separated by a shell.
Pump part (wet end) is completely sealed and therefore isolated from plating proces.
Power transmission is established by magnetic force between motor shaft and impeller.
Bearings are lubricated and cooled by liquid itself.
Mechanical seal pumps. How it works?
Impeller is directly attached to the motor shaft by shaft coupling.
Mechanical seal on pump shaft prevents liquid from coming out.
Mechanical seal is lubricated and cooled by liquid itself.
These type of pumps are not self priming and not designed to run dry or hot. Optional priming chambers and dry run protection devices
are available.
Initial start-up
Priming instructions at ooded suction:
1. Open all valves on suction and discharge side.
2. The pump should always be ooded with liquid to prevent any damage on bearings.
3. These type of pumps are not self priming. Therefore liquid level in the bath should be ample above entrance level of the pump.
4. Check for direction of rotation before start-up by shortly switching on/off.
5. Start the pump when no air remains in the pump.
6. When pumping liquid with higher density than water, start up with almost closed discharge valve to reduce power consumption.
Priming instructions at non ooded suction:
1. Ensure entrance of suction pipe is in liquid.
2. Slowly ll pump casing and suction pipe. Use discharge connection to ll.
3. Check if pump is free of air.
4. Close discharge valve and check for direction of rotation before start-up by shortly switching on/off.
5. Start the pump.
6. Wait until pump is building up pressure, and slowly open discharge valve.
Restart after power failure: Check if the pump is able to prime again. Suction pipe and pump housing should be lled.
Contaminated strainers (if applicable) can reduce ow, therefore: clean strainers regular.

Regular pump inspection
During operation all pumps should be checked regularly. Check ow, pressure, manometer indication, pipe work, hoses, hose clamps and
absorbed power by monitoring amperage of the motor. Pumps should be tted with thermal overload switch. Check pumps for any unusual
noise or vibration (this may indicate the moment of maintenance).
Maintenance precautions
To avoid dangerous or fatal electric shock hazard and to avoid injury from starting the motor unexpectedly, disconnect and lock
out power supply to the motor. Always use genuine parts to assure good performance. When taking pump apart check for
sequence of disassembly and reassembly. After having completed maintenance or repair, follow safety and installation
instructions.
Recommended maintenance schedule
The recommended maintenance schedule depends upon the nature of the uid being pumped and the specic application. If the pump is
used in a clean uid, it is recommended that the pump be removed from service and examined after six months of operation or after 1500
hours of operation. If the pump is used on uids with solids, high temperatures or other items that could cause accelerated wear, then this
initial examination should be sooner.
After the initial examination of the internal components and wear items are measured, a specic maintenance schedule can be determined.
For best results, it is recommended that the pump be removed from service annually for examination.

4.3 Filter chambers
4.3.1 Installation
Following rules should be respected when installing :
Bottom of lter chamber (by preference) is placed at the same height as bath level; this will ensure an easy medium change and prevents
unwanted emptying of tank.
1. Maximum pressure should not exceed indication on dial of manometer.
2. Maximum allowable pressure at temperature range is indicated on top of lter chamber.
3. Adjust diameter of in- and outlet of the lter to required capacity of the system.
4. Return pipe from lter chamber should be placed as far as possible from pump inlet in order to promote good bath movement.
5. Filter chamber 362 has a tiltable lid. Position of lid can be changed by positioning top ring (304).
4.3.2 Operation and Maintenance
Maximum pressure in lter chamber
The maximum pressure in Hendor lter chamber should not exceed the engraved value on top of the cover plate.
Pressure gauge
A pressure gauge is tted on most Hendor lter chambers. An anti-freeze lled chamber above a membrane separates the pressure
gauge from the process liquid. During normal operation the lter chamber regularly should be inspected for ow (dial indication on gauge).
If pressure on manometer is less than usual, the chamber below the manometer should be relled.
Topping up manometer liquid:
After removing gauge (328) and air release screw, top up casing (327) with anti-freeze.
When assembling gauge (mind O-ring 335) liquid must show up.
Put back air release screw into casing and tighten it.
If liquid does not show up repeat procedure here above. If still no liquid shows up the membrane should be replaced.
Remove gauge (328), unscrew 4 screws, take off the lid (327), replace membrane (326), ret 4 screws lightly, holding down the membrane
with unsharp object through lid, tighten 4 screws and repeat above mentioned procedure.
If pressure on the dial of the gauge is not coming back to zero, when the pump is switched off, there may exist a difference of pressure
between inside gauge and open air. To correct dial indication cut off the top of the rubber cap on top of the gauge.
4.3.3 Dismantling and reassembly
Replacement of lter elements
Depending on the type of lter, the lter element(s) should be exchanged reaching a maximum pressure difference of 1-2,5 bar.
Sequence of operation
- switch off pump (ensure pump cannot be started unexpectedly).
- close all main taps.
- open drain valve.
- open air release tap (turning CCW maximum 2 rotations) to empty lter chamber
- loosen all star buttons.
- remove or tilt the lid of the lter chamber; sometimes the gasket sticks to the chamber and extra lifting effort is required to
remove the lid.
Hendor lter chambers are equipped with cartridges, discs or bags.
After removing the contaminated lter medium it should be disposed off according to environmental guidelines.
Properly install the new lter medium to prevent by-pass of unltrated liquid.

Closing sequence
- check sealing rubber of chamber on distortion.
- close lid.
- tighten star buttons rmly crosswise.
- close drain valve, open main taps and start-up the pump.
- check unit for any leakage.
- after bleeding the unit, close air release tap.
Particular instructions series 362
- when loosening star buttons, two xed star buttons should be turned clockwise, which will slightly lift the lid (because of sticking
gasket) after removing other star buttons.
- after lifting, two star buttons have to be turned 4 times anti-clockwise in order to lift the lid by handgrip into leaning position.
Closing sequence
- check sealing rubber of chamber on distortion
- close lid by tilting down
- turn two xed star button 4 times clockwise
- tighten remaining star buttons rmly crosswise and at last two remaining xed star buttons.

1. The warranty on goods delivered by Hendor delivered for defects that are caused by manufacturing and/or materials errors is valid during
a period of a maximum of 8000 operating hours within 12 months after the delivery ex-factory by Hendor. Solely when as a consequence
of transport of the delivered goods to a destination outside Europe the putting into operation of the good does not take place immediately
after delivery, the aforementioned warranty period is extended with the duration of the transport, it being understood that the warranty
period in no case will be longer than 18 months from the delivery ex-factory. After expiry of this term any warranty becomes void.
Hendor is not liable and offers no warranty for defects that are not caused by manufacturing and/or materials errors. Each warrant
becomes forfeit if the defect is not reported in writing to Hendor within 14 days after discovery, albeit after it could reasonably have been
discovered, accompanied by a precise description of the complaint as well as the work conditions.
2. The warranty consists of replacement or repair of the defect product or parts thereof, such at the discretion of Hendor. All other costs that
must be made in connection with the replacement or repair, such as freight costs, import duties, possible costs of a service mechanic,
will be for the account of the counterparty. Products which are sent in connection with a warranty claim to Hendor, must be sent clean
and free of chemical residue and free of charge. Replacement or repair is executed in accordance with the directions of Hendor and in
the manner that it deems t. Replacement or repair shall solely be executed after permission in writing of Hendor.
3. Each warranty or liability of Hendor becomes void, if the aforementioned conditions are not complied with.
4. Warranty claims are furthermore excluded in any case if:
a) the products are used for an application not accepted in writing by Hendor or have been modied;
b) the products have not been used according to the technical manual or have been used incorrectly or inexpertly, have been
maintained insufciently or the damage or the defect is the consequence of normal wear and tear;
c) the counterparty does not comply with any obligation (nancially or otherwise) towards Hendor deriving from whichever agreement;
5. Defects in a part of the delivered do not give the counterparty the right to disapprove of the entire delivered party.
