Technical data
ConstructionVia an external signal from a sensor or a controller, the pumps allow for any configuration and control method required, that is constant pressure, temperature, flow or level.
The permanent-magnet motor has a built-in frequency converter for continuous adjustment of the pressure to the flow rate. All pumps are fitted with Grundfos permanent-magnet MGE motors that have motor efficiency class IE5 according to IEC 60034-30-2.
The range is a preset solution for quick and safe installation.
The pumps are available as single-head, TPE2, and twin-head, TPE2 D, pumps.
The pumps have PN 6, PN 10 or PN 16 flanges.
The pumps are fitted with an unbalanced mechanical shaft seal.
The power head (motor, pump head and impeller) and pump housing are held together by a specially designed clamp. The clamp allows for fast repositioning of the pump housing and fast service of the pump.
The twin-head pumps are designed with two parallel power heads. A flap valve in the common outlet port is opened by the flow of the pumped liquid and prevents backflow of liquid into the idle pump head.
As radial and axial forces are absorbed by the fixed bearing in the motor drive-end, the pump requires no bearing.
Pumps with stainless-steel pump housing, version I, are suitable for circulation of domestic hot water.

ApplicationsThe pumps have integrated speed control for automatic adaptation of performance to current conditions.
The energy consumption is thus kept at a minimum.
The pumps can operate at any duty point within the range between minimum and maximum speed.
Fig. 23 Duty range of TPE2
Depending on the application, the pumps offer energy savings, increased comfort or improved processing.
The pumps can be fitted with sensor types meeting the requirements mentioned in section 28. Accessories.
Constant curve
The pumps are factory-set to constant-curve control mode.

flows, for example boiler, heat exchanger and distribution pipe up to the first branching• primary circuit pumps in systems with large pressure losses in the primary circuit• air-conditioning systems with the following:

water flows, for example boiler, heat exchanger and distribution pipe up to the first branching, or modified to a high differential temperature between flow pipe and return pipe, for example district heating.

If an external controller is installed, the pump is able to change from one constant curve to another, depending on the value of the external signal.The pump can also be set to operate according to the maximum or minimum curve, like an uncontrolled pump:• Use the maximum curve mode in periods in which a maximum flow is required.
This operating mode is for instance suitable for hot-water priority.• Use the minimum curve mode in periods in which a minimum flow is required.
This operating mode is for instance suitable for manual night setback instead of automatic night setback.

In systems requiring a constant flow, independently of pressure drop.Examples:• chillers for air-conditioning• heating surfaces• cooling surfaces.
Constant flow rate
All
In systems requiring a constant tank level, independently of the flow rate.Examples:• process water tanks• boiler condensate tanks.

In systems with pumps operating in parallel.The multipump function enables the control of single-head pumps connected in parallel (two to four pumps) and twin-head pumps without the use of external controllers. The pumps in a multipump system communicate with each other via the wireless GENIair connection or the wired GENI connection.

Multipump systemThe multipump function enables the control of single-head pumps connected in parallel or twin-head pumps without the use of external controllers. The pumps in a multipump system communicate with each other via the wireless GENIair connection or the wired GENI connection.
You set a multipump system via a selected pump, that is the master pump which is the first selected pump.
If you configure two pumps in the system with an outlet-pressure sensor, both pumps can function as master pumps and take over the master pump function if the other fails. This provides additional redundancy in the multipump system.
You can connect all Grundfos pumps with a wireless GENIair connection to the multipump system.
The multipump functions are described in the following sections.
Alternating operation
Alternating operation functions as a duty-standby operating mode and is possible with two pumps of same size and type connected in parallel. The main purpose of the function is to ensure an even amount of running hours and to ensure that the standby pump takes over if the running pump stops due to an alarm. Each pump requires a non-return valve in series with the pump.
You can choose between two alternating operation modes:
• Alternating operation, timePump changeover to the other is based on time.
• Alternating operation, energyPump changeover to the other is based on energy consumption.If the duty pump fails, the other pump takes over automatically.Only one pump is operating at a time. The change from one pump to the other depends on time or energy. If a pump fails, the other pump takes over automatically.
Pump system:
• Twin-head pump.
• Two single-head pumps connected in parallel.The pumps must be of the same type and size. Each pump requires a non-return valve in series with the pump.
Backup operation
Backup operation is possible with two pumps of same size and type connected in parallel. Each pump requires a non-return valve in series with the pump.
One pump is operating continuously. The backup pump is operated for a short time each day to prevent seizing up. If the duty pump stops due to a fault, the backup pump starts automatically.
Pump system:
• Twin-head pump.
• Two single-head pumps connected in parallel.The pumps must be of the same type and size. Each pump requires a non-return valve in series with the pump.
Cascade operation
Cascade operation ensures that the pump performance is automatically adapted to the consumption by switching pumps on or off. The system thus runs as energy-efficiently as possible with a constant pressure and a limited number of pumps.
When a twin-head pump is running in constant-pressure control mode, the second pump head starts at 90 % and stops at 50 % performance.
All pumps in operation will run at equal speed. Pump changeover is automatic and depends on energy, operating hours and fault.
Pump system:
• Twin-head pump.
• Two to four single-head pumps connected in parallel. The pumps must be of the same type and size. Each pump requires a non-return valve in series with the pump.
Set the control mode to "Const. pressure" or "Const. curve".
Control optionsCommunication with the pumps is possible via a central building management system, Grundfos GO or control panel.
The purpose of controlling TPE2 pumps is to monitor and control the pressure, temperature, flow rate and liquid level of the system.
For further information on control options of TPE2 pumps, see page 105.
