Description

Overview

Etatron PKX series chemical dosing systems are used where a measured amount of a chemical antiscalant or sanitising agent such as liquid chlorine is required to be added to a feedwater stream.

These simple to operate pumps are solenoid driven, simple to use with high quality components and compact dimensions.

Standard features include IP65 rated polypropylene enclosure, manual air bleed pump head, an integral float sensor for chemical drum level sensing, wall or foot mounting and quiet operation.

Flow rate is set using a single rotary control knob which varies the frequency of the fixed-stroke length solenoid valve operation between 0 and 100%. Pump models are available for flow rates between 1 and 10 litres/hour with options in each flow range for differing control inputs.

Options available include:

  • Pump head with gravity type Pyrex glass valves or AISI 316/ceramic.
  • Pump head with hastelloy spring loaded ball valve using Pyrex glass or AISI 316/ceramic.
  • Further options for wetted surface materials include PVDF, EPDM, Silicone, NMR, AISI316 s/s or PTFE.

 

 

Models

PKX Models

There are several models available in the Etatron PKX series compact dosing pumps. All are supplied with a fixed power cord (removable power cord is an option except PKX-2EV). The versatile mounting bracket allows for vertical or horizontal surface mounting options.

PKX MA-A The flow rate is set through a rotary potentiometer knob which controls the dosing frequency from 0% to 100% of rated capacity The pump is supplied with a weatherproof ON-OFF switch.
PKX MA-AL The flow rate is set through a rotary potentiometer knob which controls the dosing frequency from 0% to 100% of rated capacity. This version includes a feed tank level sensing setting control.
PKX F-T This model is a reed contact proportional dosing system controlled from an external contact-free sensor such as a pulsed output flow meter. Two optional features include a volumetric proportional dose (1 injection per 1 input pulse) or a volumetric dose with a timer (programmable injection timer for each impulse received from the external sensor with a timer range of 0 to 60 seconds). There is also an optional storage tank level sensor.
PKX CC-M This model uses an external 4-20mA signal (4mA = 0% frequency, 20mA = 100% frequency). The pump has a weatherproof ON-OFF switch and there is an optional storage tank level sensor.
PKX MA/2EV The PKX MA/2EV has two separate power supplies with independent flow setting controls. Flow rate setting is made through variation to the dosing frequency through a rotary potentiometer from 0-100%.
