Digital Dosing Pump E01C – 375 to 940 L/h, up to 10 bar

Overview

The digital dosing pump E01C is the high-capacity series for bulk chemical feed. It covers 3 models, from 375 L/h · 10 bar to 940 L/h · 4 bar. First, a vector motor drives the diaphragm directly. As a result, you set the flow digitally anywhere in a 1:15666 range, and the pump repeats each dose to within ±1 % of full scale.

In addition, the E01C runs almost pulsation-free, because the motor controls the stroke speed rather than counting strokes. Slow modes at 50 % and 25 % speed therefore handle viscous chemicals up to 800 and 1500 cP.

The C series is the high-capacity range — 375 to 940 L/h with DN25 PVC connections and a 400 W drive — for bulk coagulant and disinfectant feeds. (Illustration shows the E01 series design; the E01C uses a larger housing.)

How you control the digital dosing pump E01C

You set everything on the pump itself: flow rate, pressure limits, wear-part monitoring, concentration proportioning and function switching. For plant control, the E01C offers RS485/Modbus, 4–20 mA, voltage and pulse inputs. Which of these are fitted depends on the electrical version, so we specify it with you.

Moreover, a sensor measures the conductivity inside the diaphragm and raises an alarm if the diaphragm cracks. Pipe-network pressure monitoring also flags blocked or leaking lines. Finally, a quick-release base takes the pump off its mount in seconds for service.

¹ The supplier tested at an altitude below 100 m with pure water at 20 °C. ² A back-pressure valve on the outlet increases the pressure differential. ³ Optional flow components in other materials extend the medium temperature range — ask us.

Where to use the digital dosing pump E01C

The digital dosing pump E01C feeds coagulant, flocculant, hypochlorite, chlorine dioxide precursors, acid and caustic in water and wastewater plants. It also serves cooling-water and boiler-water treatment. In addition, mining, food, chemical and manufacturing plants use it for process dosing. For example, a pH or concentration control loop can drive the pump through its 4–20 mA or Modbus input.

Why buy dosing pumps from Hadron Group

Hadron Group designs, installs and services chemical dosing systems across South Africa and the SADC region. First, we size the pump to your duty point. Then we supply the suction and injection accessories, the spares and the chemicals it will dose. Finally, we commission it on site. Every model also carries its Hadron item code, so quotes, orders and spares always refer to the same pump.

Frequently asked questions

Which digital dosing pump E01C model do I choose?

Pick the flow and back pressure your duty point needs, with some margin. For example, choose 375 L/h · 10 bar for low-flow, high-pressure lines and 940 L/h · 4 bar for high-volume, low-pressure dosing. Each option carries its own item code and price.

How does the digital dosing pump E01C differ from a solenoid pump?

A solenoid pump doses in fixed strokes, so you turn it down by stroke frequency. The vector motor of the E01, however, controls the stroke speed itself. As a result, you get a far wider setting range, smoother output and precise dosing of viscous chemicals.

Can a PLC or controller drive it?

Yes. RS485/Modbus, 4–20 mA, voltage and pulse (water-meter contact) inputs are available, depending on the electrical version. In addition, the pump reports pressure, diaphragm and wear-part alarms.

Are spares and accessories available?

Yes — diaphragms, pump heads, check-valve sets and suction or injection lines. See dosing pump spares, or quote the model when you order.
