The IX series are digitally controlled stepper motor-driven metering pumps which span the application range between small solenoid & conventional motorised metering pumps. Their electronically controlled direct-drive stepper motor provides an extremely wide capacity range. Up to 750:1 capacity turndown is possible while retaining ±1% accuracy and virtually constant chemical injection, even at low flows.a smooth flow characteristic.
Wetted materials are PTFE, PVdF with ceramic or 316 s/steel to handle virtually all common water treatment chemicals.
The IX can operate in various automatic modes including external proportional pulse, analague 4-20mA, preset batch or interval batch. Flow detection and failure alarm, flow readout in either litres/hr or strokes/min. This model also features a motor overload and diaphragm rupture sensor with two relay outputs, selectable from a preset menu, allowing the operator to customize alarm output signals. The IX also features data logging capabilities including operating time, total flow volume, power on time and number of On/Off’s. Suction stroke speeds are adjustable through 4 speeds (100%, 75%, 50% and 25%) for cavitation prevention when pumping viscous liquids.
Three sizes cover from 0.08 to 300l/hr at discharge pressures up to 10 bar.
The controller with backlit LCD display can be mounted in several different positions according to operator preference. Screwed connections are standard, with ANSI flanges also available.
