OUR CHOICE OF

DRIVES

We have the technology

Advanced technology and design underlie Watson-Marlow

hygienic pumps’ long life of quality service.

Our reliability record is maintained by features such as

brushless DC drive, a toughened LCD screen and a rugged

membrane keypad. The chemical resistance of the whole

range outlasts our competition; using a powder-coated IP66

casing that outperforms stainless steel when exposed to

aggressive fluids and cleaning agents.

Clean and reliable

Speed scaling

Programmable twin analogue inputs allow flow

pacing to be coupled with downstream quality

feedback. The second input over-rides the main

speed control, making stroke adjustment on a

diaphragm pump redundant. Drop-in diaphragm

pump replacement could not be simpler.

Accuracy

Class-leading flow control up to 3,600:1 and

simple, accurate configuration mean that your flow

will match your needs precisely. Couple that with

tube bores from 0.5mm to 25.4mm and you have

a range of unbeaten versatility.

PIN-secure process

protection

ustomize your pump setup to your precise validated

process needs and lock it. With twin Pin-secure

rocess Protection, top-level PIN-code holders retain

ull control. Calibration can also be released to

roduction staff with second-level PIN access.

Operator safety

perator safety comes first, with sturdy metal

or impact-resistant guards and drain ports for

safe disposal of spillages. Tool lockable or electronic

guard switches are standard on all pumps. Optional leak

detection is available for all models.

IP66 protection

All hygienic pumps meet the criteria for IP66

and IP66 classification: they are secure against high-

pressure washdown. IP31 wipe-down models

are also available in the 520 and 620 series.

Status outputs

Four configurable relay outputs. Monitor Run/Stop;

Rotation direction; Auto/Manual operation; general fault

alarm; automatic shut-down if the guard is opened;

leak-detected shutdown.

RS485

Full industrial-standard connectivity

with RS485 and easy-wire relays for permanent

connection to control systems including PC

and PLC.

Profibus cased

pumps

No point-to-point wiring and a simple 9-pin

ROFIBUS connector means real-time, two way

communication for pump control and status

feedback, including a full range of diagnostic

information. The 520, 620 and 720 series pumps

run from the same GSD file which enables true

process scaling. Pumps communicate at the full

PROFIBUS bus speed range, automatically

detecting and adjusting to fit your network.

Control range

520: 0.1-220 rpm; 620: 0.1-265 rpm; 720:

0.1-360rpm

Voltage/frequency

Filtered 100-120V/200-240V 50/60Hz 1ph

Maximum voltage

fluctuation

±10% of nominal voltage. A well regulated

electrical mains supply is required along with

cable connections conforming to the best

practice of noise immunity

Installation category

(over voltage)

Power consumption

520: 135VA; 620N: 250VA; 720N: 350VA

Full load current

520: <0.6A at 230V; <1.25A at 115V;

620: <1.1A at 230V; <2.2A at 115V;

720: <1.5A at 230V; <3.0A at 115V

Eprom version

Accessible through pump software

Enclosure rating

IP66 to BS EN 60529; Equivalent to NEMA 4X

to NEMA 250* (indoor use). Suitable for heavy

industrial, process and harsh environments.

The drive uses a Gore membrane vent to

equalise the pressure inside the enclosure and to

prevent ingress of water and corrosive vapours.

Operating temperature

5C to 40C, 41F to 104F

Storage temperature

520: -40C to 70C, -40F to 158F;

620, 720: -25C to 65C, -13F to 149F

Maximum altitude

2,000m, 6,560ft

Humidity (condensing)

10% - 100% RH

Noise

520, 620: <70dB(A) at 1m; 720: <85dB(A) at 1m
