Submersible recirculation pumps 1
1. Introduction
General descriptionThis data booklet describes Grundfos submersible recirculation pumps, type SRP.
Fig. 1 SRP
The Grundfos submersible recirculation pumps are designed for the transfer of liquids of low to medium viscosity.
The pumps are intended for pipe diameters between 12 and 36 in, incorporating motors of 1.1 hp (0.8 kW) to 32.6 hp (24 kW). Adaptation to other diameters is possible.
The pumps incorporate a squirrel-case induction motor, a planetary gear and a cast stainless-steel propeller ensuring high resistance to wear and corrosion. The 3-dimensional optimised hydraulic design ensures high efficiency.
ApplicationsGrundfos SRP recirculation pumps are designed for the pumping of sludge from one tank to another in sewage treatment plants as well as for other pump applications involving a high flow rate and low head.
Constructional features• Strong axial gear in slim design for high hydro-
dynamic efficiency
• integrated overload and overheating protection
• integrated water-in-oil sensor
• cast stainless-steel propeller
• good self-cleaning capabilities.
Operating mode• Continuous operation when fully submerged
• intermittent operation with max. 20 starts per hour.

3. Product description
Features
Motor
The motor is a 2- or 4-pole squirrel-cage induction motor. The stator is supported by two ball bearings.
The water-tight cable entry prevents moisture ingress down to a depth of 66 ft (20 m).
Starting method
In general, we recommend to use soft starter or variable speed drive to minimise wear and tear on the equipment.
Continuous operation: The SRP recirculation pumps are suitable for direct-on-line starting.
Intermittent operation: The SRP pumps are suitable for direct-on-line starting, provided the maximum number of starts per hour is not exceeded. To minimise wear and tear on the equipment, we recommend to start the SRP pump via soft starter or variable speed drive.
Gearbox
The planetary gearbox is positioned between the motor and the propeller.
The gearbox is oil-filled, and the gear wheels are hardened to ensure long life. See the installation and operating instructions for information on oil type, oil quality and oil change intervals.
The gearbox/shaft seal housing has water-in-oil sensor and external relay which together can give an alarm or cut out the motor in case of water ingress.
Bearings
Motor: Single-row ball bearings.
Gear: Tapered roller bearings.
Shaft seal
To prevent ingress of the surrounding liquid, the recirculation pumps have shaft seal(s) and possibly seal rings fitted around the propeller shaft. In addition, the recirculation pumps also have a shaft seal or two seal rings between the shaft seal housing/gearbox and the motor.
Shafts
See below table for motor and gear shaft.
Propeller
The three-blade, self-cleaning propeller is made of cast stainless steel.
Power cables
The specific cable can be found in the tables in section Technical data, 440-480 V, page 46.
Cable entry
Elastomer, 70 shore hardness.
Sensors
Standard SRP pumps incorporate three bimetallic PTO thermal switches (PTO = Protection Thermique à Ouverture). See fig. 3.
PTC sensors are available on request.
The gearbox is monitored for the ingress of water by a water-in-oil sensor incorporated as standard in the gearbox/shaft seal housing. Via an external relay, the sensor triggers an alarm signal and/or disconnects the motor.

Wiring diagrams
Wiring diagram, three thermal switches (PTO)
Fig. 3 Wiring diagram, three thermal switches
Water-in-oil sensorThe gearbox is monitored for the ingress of water by a water-in-oil sensor incorporated as standard in the gearbox/shaft seal housing. Via an external relay, the sensor triggers an alarm signal and/or switches off the motor.
We recommend you to connect the water-in-oil sensor to a Grundfos ALR-20A relay or similar type. The Grundfos ALR-20A is available as an optional accessory. See10. Accessories, page 52.
Note: Being an electronic component, the water-in-oil sensor must not be tested with an ohmmeter or other measuring instrument.
ALR-20/A relay
Fig. 4 ALR-20/A relay
Dimensional sketch, ALR-20/A relay
Fig. 5 Dimensions of ALR-20/A relay
Settings
The sensitivity of the ALR-20/A relay can be tested as follows:
1. Turn the adjusting screw a until the indicator light b of the relay is on. See fig. 4.
2. Turn the adjusting screw in the opposite direction until the indicator light is off.
3. Turn the adjusting screw another 60 ° (in the same direction as under step 2).
Note: The cable between the relay and the pump must not exceed 164 ft (50 m) in length. An external alarm indicator, if any, must be connected to the potential-free output, terminals 1 and 3 or 4.
For further information, see the data sheet for ALR 20/A.

4. Selection of product
Ordering a recirculation pumpFew product numbers need to be selected to make the order complete:
• SRP recirculation pump (standard)
• custom-built variants (option)
• mechanical installation accessories
• electrical accessories, leak detector relay and variable speed drive.
Standard pumpSee below example of what you get when you order a standard SRP pump:
• Recirculation pump
• cable, 30 ft (10 m)
• paint, graphic grey, NCS8005-r-80b 350 μm thickness
• three bimetallic PTO thermal switches, one in each motor winding
• one water-in-oil sensor incorporated in the gearbox.
Note: In WebCAPS you can find product specific data via the product number, e.g. 97754453.
VariantsIf a longer cable or a shielded cable is required, the pump is no longer a standard product. A list of variants can be found in Variants, page 20.
AccessoriesFor selection of the correct accessories, see10. Accessories, page 52.
Note: The accessories are not fitted from factory.
ControllerControl unit ALR-20/A can be used in combination with SRP pumps.
Selecting an SRP pumpThe selection guide is for guidance only. For detailed information, please contact your local Grundfos representative.
The selection curve charts for the Grundfos SRP pumps shown later in this section are based on the following:
• system description and layout
• flow rate, Q, GPM
• geometrical head, Hgeo, in ft (Hgeo = H2 - H1).
Fig. 6 System layout
Head loss can be calculated on the basis of information in the system layout.

8. Positioning
General descriptionSubmersible recirculation pumps must be positioned properly in order to obtain efficient operation and prevent vibrations resulting in wear and/or reduced pump performance.
Submersible recirculation pumps are normally equipped with a hydraulic inlet connecting to the connection flange.
Fig. 32 Dimensions of connecting pipe
H/Emin = distance from bottom of tank to middle of connecting pipe.
If the pump is operating at low water levels, install a vortex shield in order to prevent the pump from sucking air into the propeller. A vortex shield is available as an accessory.
Fig. 33 Installation with vortex shield
HAbove = distance from top of pump rack to surface of liquid.

Sizing
This section is based on different fields of application and installation examples and gives easy step-by-step instructions in how to size a product:• Select the most suitable and efficient pump for your
installation.• Carry out advanced calculations based on energy,
consumption, payback periods, load profiles, life cycle costs, etc.
• Analyze your selected pump via the built-in life cycle cost tool.• Determine the flow velocity in wastewater applications, etc.
Replacement
In this section you find a guide to selecting and comparing replacement data of an installed pump in order to replace the pump with a more efficient Grundfos pump. The section contains replacement data of a wide range of pumps produced by other manufacturers than Grundfos.
Based on an easy step-by-step guide, you can compare Grundfos pumps with the one you have installed on your site. When you have specified the installed pump, the guide will suggest a number of Grundfos pumps which can improve both comfort and efficiency.
CAD drawings
In this section, it is possible to download 2-dimensional (2D) and 3-dimensional (3D) CAD drawings of most Grundfos pumps.
These formats are available in WebCAPS:
2-dimensional drawings:• .dxf, wireframe drawings• .dwg, wireframe drawings.
3-dimensional drawings:• .dwg, wireframe drawings (without surfaces)• .stp, solid drawings (with surfaces)• .eprt, E-drawings.
WinCAPS is a Windows-based Computer Aided Product Selection program containing detailed information on more than 220,000 Grundfos products in more than 30 languages.
The program contains the same features and functions as WebCAPS, but is an ideal solution if no internet connection is available.
WinCAPS is available on DVD and updated once a year.
