2.5.6 Electric motor
The electric motor has an extended shaft, on which the impeller is mounted. The forces
on the impeller are absorbed by the motor bearings. The bearings are dust-proof and
greased for life, so they are maintenance-free. The protection class for all motors is IP
55. The electric motors are equipped as standard with an aluminium terminal box.
➢
All electric motors are suited for connection to frequency control.
2.6 Ecodesign Minimum Efficiency Requirements Water Pumps
• Directive 2005/32/EC of the European Parliament and of the Council;
• Commission regulation (EU) No 547/2012 Implementing Directive 2009/125/EC of
the European Parliament and of the Council with regard to ecodesign requirements for
water pumps.
2.6.1 Introduction
SPX Flow Technology Assen B.V. is an associate member of the HOLLAND PUMP
GROUP, an associate member of EUROPUMP, the organization of European pump
manufacturers.
Europump promotes the interest of the European pump industry with the European
institutions.
Europump welcomes the aim of the European Commission to reduce eco-impact of
products in the European Union. Europump is fully aware of the eco-impact of pumps in
Europe. For many years the ecopump initiative is one of the strategic columns in the work
of Europump. From the first of January 2013 the regulation is coming into force
concerning minimum required efficiencies of rotodynamic water pumps. The regulation
sets minimum efficiency requirements on water pumps set out under the Ecodesign
Directive for energy related products. This regulation mainly addresses manufacturers of
water pumps placing these products on the European market. But as a consequence
customers may also be affected by this regulation. This document gives necessary
information related to the coming into force of the water pump regulation EU 547/2012.
2.6.2 Implementing Directive 2009/125/EC
• Definitions:
“This Regulation establishes eco-design requirements for the placing on the market of
rotodynamic water pumps for pumping clean water, including where integrated in other
products.”
“Water pump” is the hydraulic part of a device that moves clean water by physical or
mechanical action and is of one of the following designs:
• End suction own bearing (ESOB);
• End suction close coupled (ESCC);
• End suction close coupled inline (ESCCi);
• Vertical multistage (MS-V);
• Submersible multistage (MSS);”
‘ End suction water pump ’ (ESOB) means a glanded single stage end suction
rotodynamic water pump designed for pressures up to 1600 kPa (16 bar), with a specific
speed ns between 6 and 80 rpm, a minimum rated flow of 6 m
3
/h, a maximum shaft
power of 150 kW, a maximum head of 90 m with nominal speed of 1450 rpm and a
maximum head of 140 m with nominal speed of 2900 rpm;
‘ End suction close coupled water pump ’ (ESCC) is an end suction water pump of which
the motor shaft is extended to become also the pump shaft;
