1.5 Instructions for transport and storage
1.5.1 Weight
A pump or a pump unit is generally too heavy to be moved by hand. Therefore, use the
correct transport and lifting equipment. Weight of the pump or pump unit are shown on
the label on the cover of this manual.
1.5.2 Use of pallets
Usually a pump or pump unit is shipped on a pallet. Leave it on the pallet as long as
possible to avoid damages and to facilitate possible internal transport.
! When using a forklift always set the forks as far apart as possible and lift the
package with both forks to prevent it from toppling over! Avoid jolting the
pump when moving it!

CombiProLine
1.5.3 Hoisting
When hoisting a pump unit OH3 or pump unit OH5 the straps must be fixed in
accordance with figure 1 and figure 2.
When lifting a pump unit always use a proper and sound lifting device,
approved to bear the total weight of the load! Never go underneath a load
that is being lifted!
! If the electric motor is provided with a lifting eye, this lifting eye is intended
only for the purpose of carrying out service activities to the electric motor!
The lifting eye is designed to bear the weight of the electric motor only!
It is NOT permitted to lift a complete pump unit at the lifting eye of an electric
motor!

2 General
2.1 Pump description
The CombiProLine represents a range of vertical "heavy duty" centrifugal pumps. The
design of this range of pumps is based on the guidelines for: "Centrifugal Pumps for
Petroleum, Petrochemical and Natural Gas Industries" from the "American Petroleum
Institute" otherwise known as the API Standard 610 (identical to ISO 13709). The
CombiProLine range therefore meets the high requirements which have been set by the
refineries and the petrochemical industry.
The API 610 contains important technical guidelines in order to guarantee optimum
reliability. This pump amply complies with these requirements. This has been
demonstrated through extensive research and can be supported on the basis of
advanced methods of calculation.
2.2 Applications
• In general, this pump can be used for thin, clean or slightly polluted liquids. These
liquids should not affect the pump materials.
• The maximum allowed system pressure and temperature and the maximum speed
depend on the pump type and the pump construction.
• Further details about the application possibilities of your specific pump are mentioned
in the order confirmation and/or in the data sheet enclosed with the delivery.
• Do not use the pump for purposes other than those for which it is delivered without
prior consultation with your supplier.
Using a pump in a system or under system conditions (liquid, working
pressure, temperature, etc.) for which it has not been designed may hazard
the user!

2.4 Serial number
Serial number of the pump or pump unit are shown on the name plate off the pump and
on the label on the cover of this manual.
2.5 Construction
The pump has a modular design. The main components are:
• Pump casing
•Impeller
• Shaft sealing
•Bearing
In general for each individual pump type there is only one design of the pump casing and
the impeller. So, the hydraulic performance is fixed. However for several pump types
there has been developed an additional “low’ or “high flow” design. The required
capacity and head are obtained by pump speed selection and, if necessary, reduction of
the impeller diameter.
The pumps are divided into three bearing groups. The OH3 pumps each bearing group
only has one pump shaft and one bearing arrangement. The OH5 pump is provided by
the motor bearings. The selection of the pump/motor combination is such that the
bearings of the applied electric motors can absorb the axial and radial forces without the
bearing life being affected.
The pumps are also standardized into six groups with the same connection for the pump
casing and pump cover, depending on the nominal impeller diameters. For each
combination of shaft and nominal impeller diameter there is one pump cover, in various
materials, and for OH3 pumps one bearing bracket which is made from carbon steel.
The various designs of pumps are created by the addition of shaft seal “cartridges”.
These “cartridges” are standardized in the same three groups as the pump shafts and
are designed in accordance with API 682 (identical to ISO 21049).
In addition to this various material varieties can be used for components which come into
contact with the pumped liquid.
2.6 Pump casing
On the suction side of the impeller the pump casing is provided with a renewable wear
ring. An anti-rotation partition is fitted into the inlet. The centering edge for the pump
cover is located on the outside of the packing for the pump casing and does not
therefore come into contact with the liquid.
The suction and discharge flanges are designed and machined in accordance with
ASME B16.5 300 lbs RF (ISO 7005 PN50), and it is also possible to supply the flanges
drilled in accordance with the ASME B16.5 150 lbs RF (ISO 7005 PN20). The outside
diameter and the thickness of the inlet and outlet flanges are, in this case, in accordance
with ASME B16.5 300 lbs. The surface finish of the flanges is according ASME B16.5
requirements. The drain of the pump casing is a “butt-welded” flanged design coherent
to the pump casing’s pressure class.

16 General CRL/EN (1810) 2.2
2.7 Impeller
The back of the closed impeller is provided with back vanes in order to limit the pressure
on the shaft seal and to allow the flushing liquid to circulate. Contamination of the shaft
seal is also prevented. On the inlet side the impeller is provided with an interchangeable
wear ring. Running clearances meet the requirements of API 610.
2.8 Pump cover
The pump is designed to fit any seal type in accordance with API 682. In collaboration
with various suppliers of mechanical seals the design has been closely evaluated in order
to be able to build in the required variants.
2.9 Wear rings
Both the impeller and the pump casing are fitted with a renewable wear ring. The impeller
wear ring has a hardness at least 50°Br over the casing wear ring. The rings are secured
by three lock screws.
2.10 Mechanical seal
The various designs of pumps are created by the addition of shaft seal "cartridges".
These "cartridges" are standardized in the same three groups as the pump shafts and are
designed in accordance with API 682.
2.11 Bearing OH3 pump
• The bearing construction consists of two angular contact bearings (in "O"
arrangement) combined with a cylindrical roller bearing. The bearings are grease
lubricated. The bearings on the coupling side with which the axial force is taken up are
retained on the shaft by a shaft nut. The outer ring of these bearings is retained by the
bearing cover.
• The cylindrical roller bearing on the impeller side takes up radial forces and is mounted
"floating" on the outer ring. As a result of this the machining tolerances and expansions
can be easily accommodated. The bearing arrangement is sealed by labyrinth rings.
2.12 Coupling OH3 pump
Pump and motor are coupled by means of a flexible coupling with spacer sleeve
('spacer'). After the guards and spacer have been removed, the rotating part of the pump
can be easily dismantled as a whole without having to disconnect the electric motor or
the piping. This construction is called the Top Pull Out principle.
2.13 Application area
The application area globally looks as follows:,
However, the maximum allowable pressures and temperatures depend strongly on the
selected materials and components. Also working conditions may cause differences.

Capacity 470 m3/h
Discharge head 160 m

2.14 Re-use
The pump may only be used for other applications after prior consultation with
SPXFLOW or your supplier. Since the lastly pumped medium is not always known, the
following instructions should be observed:
1 Flush the pump properly.
2 Make sure the flushing liquid is discharged safely (environment!)
Take adequate precautions and use the appropriate personal protection
means like rubber gloves and spectacles!
2.15 Scrapping
If it has been decided to scrap a pump, the same flushing procedure as described for
Re-use should be followed.
