High Pressure Centrifugal Pumps 

Standard and Electronic Pumps

The name Wilo equally stands for 

tradition and competence. It 

represents more than 70 years of 

Pumping Perfection and stands 

for such eminent innovations 

such as the first ever electronically 

controlled heating circulating 

pump. Wilo were the first to apply 

the glandless pump design in the 

fields of water supply and pressure 

boosting and to develop the 

first Inox/Composite submersible 

pump for use in the fields of sanitary 

engineering. 

Wilo AG was established by 

merger of the 1996-founded Wilo- 

Salmson AG with Wilo GmbH. 

Wilo AG is the principal managing 

body of all activities of the associated 

group of companies which, 

with annual revenues of approximately 

€ 536 million, ranks 

among the worldwide leading 

manufacturers of pumps and 

pumping systems. A staff of more 

than 3000 employees represent 

the group with currently 36 subsidiaries 

in 32 countries. 

Activities in all the three fields, 

heating, water supply and 

sanitary engineering are focussed 

on absolute customer orientation 

and an area-covering service network 

at home and abroad. 

The acknowledged competence 

of Wilo results from its unique 

product range, intensive knowhow 

and an effective quality 

management. 

Since 1991 Wilo have been ISO 

9001 certified, since 1999 also to 

ISO 14001 and VDA 6.1.

Construction Materials 

Pump base cast iron** / SS AISI 316L 

Diffusers SS AISI 304 / 316L 

Pressure casing SS AISI 304 / 316L 

Shaft SS AISI 316L. 

Seals EPDM/Viton 

Mech.seal Tungstencarbide/carbon 

** Cataphoresic coating 40 µm on series 16../32.. 

Design 

Multistage non self-priming vertical high 

pressure centrifugal pump of Inline 

design, PN 16/25 with equally sized suction 

and discharge ports. Stage construction 

with stainless steel impellers, diffusers 

and pressure casing. Pump stub 

shaft and motor spindle of the IEC-standards 

motor are directly close coupled. A 

separate stool mounted roller bearing 

serves to balance the axial forces so that 

any make of IEC-standard motor (mounting 

frames V 1 or V 18) can be used. 

Maintenance-free, bi-directional mechanical 

seal. All relevant parts suitable to 

handle food-compatible fluids. 

Motor / Electric Wiring 

IEC-standards threephase motor, enclosure 

IP 55, insulation class F, V18 frame 

up to size 5.5 kW, V1 frame for 7.5kW and 

larger. Up to 4 kW 220–254 V∆ and 380– 

440 VY/60 Hz. 5.5 kW and larger 380–440 

V∆ /60 Hz. Permissible voltage tolerance 

± 10%.

Product Features of Wilo-Economy MHIE 

46 Wilo-Economy MHIE 


Electronic Pumps 

Some of the sound reasons to decide on the 

Wilo-Economy MHIE pump series! 

The pump in general 

● Integrated frequency converter! 

● Monobloc design with common motor/pump shaft! 

● All fluid-contacted parts of grades 304 (1.4301) or 316L (1.4404) stainless steel! 

● Simple pump selection! 

4 MHIE types only cover the duty range of more than 14 MHI types 

● High operating reliability! 

Due to bi-directional mechanical seal 

Motor and automatic controls 

● Extremely wide control range! 

Super synchronous motor speeds offer an output control frequency range 

from 26 to max. 65 Hz, also at a frequency input of 50 Hz. 

● Integrated air-cooled frequency converter! 

Provides any motor speed between 1500 and 3770 rpm 

(corresponding to a control range from 40 to 100%) 

● Simple speed setting by means of a potentiometer! 

Remote control without external sensors or setpoint adjustment 

with the aid of an external pressure sensor (impulse signal 4-20 mA or 0-10 V) 

respectively. 

● Remote speed control possible! 

Via an impulse signal 0-10 V or 4-20 mA. 

● Integrated motor protection by PTC sensors! 

● Permanent operating status information! 

By means of 3 LEDs in the frequency converter casing. 

● Integrated low water level control! 

With cut-out via the power graph of the motor control electronics. 

● Collective run and fault signals! 

(initiated by volt-free contacts) 

● Remote On/Off control! 


● EMV! 

Meeting the requirements of EN 50081 T 2 and EN 50082 T 2. 

(EN 50081 T 1optionally possible). 





Non self-priming pumps with adaptive 

frequency converter 


e.g. Wilo-Economy MHIE 803 

MHIE Multi-stage horizontal high pressure 

centrifugal pump directly driven 

by a flange-mounted motor. 

All parts in contact with the fluid 

made of stainless steel. Motor

Functions 

The pump is equipped with a three phase 

motor with integrated air-cooled frequency 

converter enabling an infinitely variable 

speed control between 40 and 100% 

(relating to a speed range from 1500 rpm 

to 3770 rpm) of the rated motor speed. 

Motor and speed controller are suitable 

for wiring to a 3 ~ 400 V / 50 or 60 Hz 

mains power supply. The permissible voltage 

tolerance is ±10%. 

All motors are equipped with comprehensive 

PTC motor protection. 

Low water will be detected by the motor 

control electronics; motors will in such 

event be automatically switched off. 

Current operating conditions will be indicated 

by three LED's integrated in the frequency 

converter panel. 

The pump can be run at different operating 

modes. The respectively required 

mode can be set by means of three DIP 

switches. 

1. Potentiometer control 

In this mode, which is possible without 

any further extras, the required motor 

speed is preselected by a potentiometer 

located inside the terminal box. It is 

recommended to make the setting to the 

required performance with the aid of suitable 

test tools (e.g. pressure gauges). 

The pump, now running at the preselected 

max. speed, will react in the same way 

as a fixed speed pump, i.e. it will operate 

along the preselected curve with the duty 

point always at the intersection with the 

currently effective system curve. 

(refer also to Fig. A) 

The factory-provided 'Remote On/Off 

control' is additionally available when 

operating in the potentiometer control 

mode. 

2. Pressure control 4 – 20 mA 

This mode requires an external analogue 

pressure sensor/transmitter (accessories) 

with which the control mode p = constant 

can be achieved (refer also to Fig. B). The 

required pressure setpoint value can be 

set by the potentiometer located inside 

the terminal box. A control signal < 2 mA 

will be valuated as a broken wire by the 

control electronics. Zero flow conditions 

will also be detected by the control electronics. 

At zero flow the pump will be switched 

off. On the system pressure dropping 

below the setpoint level the pump 

will be automatically restarted in order to 

maintain a constant pressure.

4. Remote control operation 4 - 20 mA 

or 0 - 10 V respectively 

To be applied in such cases where it is 

required for the direct control of the 

speed/frequency and thus the hydraulic 

performance of the pump from a central 

management system (BMS). The remote 

setpoint control can be applied to control 

pump operation to any duty point within 

the duty field. In this mode signals < 1 V or 

< 2 mA respectively will be valuated as 

'Remote Off'. The potentiometer, required 

for speed / frequency / pressure settings 

has no functions in the remote control 

operating mode.

Application 

The use of the bypass set always makes 

sense when the fluid contains a high 

amount of air or oxygen or shows a trend 

to gas formation. 

The bypass set serves to mainly avoid air 

or gases collecting in the upper region of 

MVI pump hydraulics where the mechanical 

seal is located. 

Typical applications where the use of 

the bypass installation is beneficial to 

the user are: 

Handling of hot condensate / pressure 

boosting where pump(s) displace water 

from atmospherically open break tanks. 

Application 

To upgrade water supply/pressure booster 

sets with series MVISE, MVIE and 

MHIE to be capable for automatic pressure-activated 

operation. The sensor to be 

installed at the discharge side of the 

pump. 

Note: Kindly observe the installation 

guide set out in the operating and maintenance 

instructions for the respective 

pump types. 


The set consists of 2 couplings incl. 

screws, seals and O&M manual.
