E+ Series Dosing Pump 3.4 Litres/Hr @ 10 Bar

FLOW
3 – 600 GPD (0.50 – 94.6 LPH) 0.13 – 25 GPH
 
PRESSURE
20 – 300 PSI (1.3 – 21 BAR)

The Series EPlus range is identical to the Series E range in terms of physical size, weight, number of models, output and pressure ranges - 0.5 litres/hour @ 21 bar to 94.6 litres/hour @ 2 bar with a turn down ratio of 100 : 1.

The Pulsation Series E Plus provides manual control over stroke length and stroke rate as standard features, with the flexibility to choose between 4-20mA and external pace inputs for automatic control. Metering performance is consistent within ± 2% of maximum capacity.

With over 25 years of proven excellence, Pulsatron pumps are recognized with agency approvals including ETL, ETL Sanitation, CE, and NSF 61 (for PVDF material and PVC Degassing Head models).

Features

• Dosage varies linearly, from lowest at 4 mA to highest at 20 mA.
• Auto/Off/Manual selection switch with indicator lights.
• Built-in circuit protection with a panel-mounted fuse for easy access.
• Clear hinged cover over controls for protection against water and dust ingress.
• Optional external pacing with a stop function that can be triggered by an impulse water meter or a level switch in the chemical holding tank.
• Optional 4-20mA signal actuation with stop function, allowing dosage to vary in proportion to external equipment signals, such as from boiler modulating feed valves.
• Automatic control with 4-20mADC direct or external pacing with stop function.
• Manual control via adjustable stroke rate and stroke length.
• Highly reliable timing circuit.
• Solenoid protection with thermal overload and auto-reset.
• Water-resistant for both outdoor and indoor applications.
• Guided ball check valve systems to minimize backflow and enhance priming performance.
• Durable, leak-free bleed valve assembly for safe and easy priming.
• Optional External Pacing option - i.e. actuation via an impulse water meter - with stop function. The stop function accepts an input from a level switch in the chemical holding tank such that the pumpwill cease operating should the level switch indicate that the chemicals have run out. *Optional 4 to 20mA signal actuation with stop function. This offers that ability to accept a signal for an external piece of equipment - e.g. some boiler modulating feed valves emit a 4 to 20mA signal, which can be used to ensure that dosage of chemicals varies in direct proportion to the flow of water into the boiler.

*NOTE: ONLY ONE OF THESE OPTIONS - NOT BOTH CAN BE UTILISED AND MUST BE SPECIFIED AT TIME OF ORDER
