Grundfos Vertical In-Line Centrifugal Pumps - TP, TPE Series

Product Description:
Grundfos TP and TPE vertical in-line pumps are used in a variety of applications. The pumps are all single-stage, in-line centrifugal pumps with standard motors and mechanical shaft seals. The pumps are of the close-coupled type, i.e. pump and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid than similar pumps of the canned rotor type.

Two different models of vertical in-line pumps are available. Please note that there are a number of specific product variants available for each model. Detailed information on these variants can be found in Grundfos Product Center.

Applications
These vertical in-line pumps are used in commercial buildings for air conditioning and heating applications.

The pumps are all single-stage, in-line centrifugal pumps with standard motors and mechanical shaft seals. The pumps are of the close-coupled type, i.e. pump and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid than similar pumps of the canned rotor type.

Features and Benefits
• Optimised hydraulics for high efficiency
• Reduced power consumption
• High-efficiency motors
• TP pumps are fitted with high-efficiency motors
• High-efficiency motors provide reduced energy consumption
• 2-pole and 4-pole TP pumps from 0.75 kW to 375 kW have IE3 motors (By March 2012)
• Top-pull-out design
• Easy dismantling for service
• In-line design
• Unlike end-suction pumps, in-line pumps allow the use of straight pipework, which often results in reductions in installation cost and amount of space occupied
• Hydraulically and mechanically balanced impeller (Series 300 and 400)
• The impeller is hydraulically and mechanically balanced to increase the life of motor bearings and shaft seals
• Pump housing and pump head/motor stool are electro-coated
• Improved corrosion resistance
• TPE, TPED – pumps with built-in frequency converter
• Reduced power consumption
• TPE and TPED motors are based on IE3 motors (except 18.5, 4-pole).

Product Specification:
Model: TP pump:
This pump model is notable for its high levels of reliability and efficiency. Quiet, highly-efficient IE3 motors are standard components. All TP pumps are electro-coated to ensure high corrosion resistance.

• TP/TPE 50 Hz:
- From 0.12 kW to 630 kW – TPE up to 22 kW
- Capacities of up to more than 4500 m3/h
- Head up to 170 m

• TP/TPE 60 Hz:
- From 0.37 kW to 315 kW – TPE up to 22 kW• Capacities of up to 1250 m3/h• Head up to 235 m

Model: TPE pump:
The main difference between TP and TPE pumps is the motor. TPE motors have a built-in frequency converter, allowing different control methods to be employed. TPE pumps offer benefits with respect to energy savings and increased comfort.

• TPE Series 1000:
- Suitable for applications where a sensor in the system controls the pressure, temperature or flow rate
- Very suitable for larger systems and customised systems

• TPE Series 2000:
- Easily commissioned and installed plug and pump solution
- Have a factory-fitted differential sensor
- Are factory-set to proportional pressure control
- Continuously adjust the pressure to fit the current demand
