The fluid technology specialist

Bürkert has launched the

successor to its type 8021 pulse

divider, as well as for the type

8023 flow transmitter. With

microcontroller-driven electronics,

the new type 8022 combines

both functions in a single device.

The type 8022 flow transmitter

and pulse divider is an electronic

module which can display and

further process the flow measured

by sensors of types 8020, 8030 or

8070. The device can be mounted

directly on top of the sensor,

where it converts the pulses from

the sensor into standard signals

for further processing, for example

by a control system. Additional

expense for cabling and for

documentation of the connec-

tion between the sensor and the

transmitter becomes unneces-

sary. Depending on the model,

the flow transmitter/pulse divider

is equipped with a removable

control unit with display. This

shows the measured flow on a

selectable unit on the device and

allows parameter settings

With the new type 8022, Bürkert

is offering in a single device

the choice between a current

or pulse output directly at the

flow sensor. The type of electrical

connection can be either via cable

gland or an M12 connection.

Additional flexibility is provided

by the optional display/operating

module, which can be used for

configuration and flow display.

HVAC power saver series

Pump forum call for papers

The Wilo-Stratos GIGA launched

by Wilo SE is the first pump

from their new high-efficiency

series for the upper performance

range in heating, cold-water and

cooling applications.

The company claims that

approximately 8,000 kg CO2

per year, as well as €85,000

electricity costs per pump

can be saved over 15 years

compared to conventional

uncontrolled pumps (based on

the load profile ‘Blauer Engel’).

Wilo claims that the series is a

completely new development.

Glanded pumps are driven

by power-saving EC motors

for the first time. The pumps’

hydraulics is optimally adjusted

to the motor technology.

According to the specifications

of the manufacturer, the pumps

reach a particularly high total

efficiency based on a motor

efficiency of up to 94% at a

nominal motor power of 4.5 kW.

The motor’s energy efficiency

is based on a new high-

efficiency drive concept, the

High Efficiency Drive (HED) from

Wilo and according to IEC TS

60034-31 Ed.1can out-perform

the limit of the upcoming

efficiency class IE4.

The VDMA Pumps + Systems

Association next Pump Users

International Forum will take

place from 27 - 28 September

2012 in the Congress Centre of

Düsseldorf, Germany. Interested

parties from the pump applica-

tion, pump manufacturing, engi-

neering and science fields are

requested to submit proposals for

technical papers. The closing date

is 10 December 2011.
