• Page 7: Installation

  3.0 — INSTALLATION a. — Install the pump in a dry place and well away from sources of heat and, in any case, at environmental tem- peratures not exceeding 40°C. The minimum operating temperature depends on the liquid to be pumped, bearing in mind that it must always remain in a liquid state.

• Page 8: Injection Valve Installation Diagram

  Fig. 8 Whenever the pump is dismantled from the pipework, you will be well advised to replace the caps on the connectors to avoid residual liquid being spilled. Before attaching the delivery hose to the plant, prime the metering pump by going through the sequence shown in Fig. 8. Before finalizing the installation of the dis- charge hose, make sure that the pump strokes will not cause it to move and bump into rigid bodies.

  4.0 — MAINTENANCE 1. Periodically check the chemical tank level to avoid the pump operating without liquid. This would not dam- age the pump, but may damage the process plant due to lack of chemicals. 2. Check the pump operating condition at least every 6 months, pump head position, screws, bolts and seals; check more frequently where aggressive chemicals are pumped, especially: — pulse and power L.E.D.;…

• Page 11: Microcontrolled Metering Pump With Ph Controller

  DLX-pH/M • DLXB-pH/M Fig. 13 6.0 — MICROCONTROLLED METERING PUMP WITH PH CONTROLLER This unit is dosing pump with integral pH controller designed to measure, control and regulate the pH value. The pump works on an ON/OFF system controlled by a microcontroller to stop dosing once the pH value reach- es set point.

• Page 12: Level Control

  6.4 – LEVEL CONTROL The dosing pump is supplied with level control setting and upon request floating level switch. When the level of the additive is lower than the switch, level alarm and yellow led are ON: the pump is OFF. The level control alarm goes ON with 5 seconds delay.

  6.10 – ACTIVATION/DISACTIVATION OF THE FUNCTIONS Pushing the F button, on display will appear the operating function (the first is F1) and its corresponding state. D means disactivated and A means activated. With the RIGHT button it’s possible to activate the function, while with the LEFT button to disactivate. To confirm the choice press F and if the function have been change this is recorded, otherwise it goes to the next function up to F3 then the pump exits from the function menu and goes in measuring mode.

  DLX-Rx/M • DLXB-Rx/M Fig. 15 7.0 — MICROCONTROLLED METERING PUMP WITH Rx CONTROLLER This unit is dosing pump with integral Rx controller designed to measure, control and regulate the Rx value. The pump works on an ON/OFF system controlled by a microcontroller to stop dosing once the Rx value reaches set point.

• Page 15: Level Control

  7.4 – LEVEL CONTROL The dosing pump is supplied with level control setting and upon request floating level switch. When the level of the additive is lower than the switch, level alarm and yellow led are ON: the pump is OFF. The level control alarm goes ON with 5 seconds delay.

  8.0 — TROUBLE-SHOOTING COMMON TO DLX — DLXB SERIES PUMPS 8.1 — MECHANICAL FAULTS As the system is quite robust there are no apparent mechanical problems. Occasionally there might be a loss of liquid from the nipple because the tube nut has loosened, or more simply the discharge tubing-has broken. Very rarely there may be losses caused by the breakage of the membrane, or by the membrane seals in which case they have to be replaced by disassembling the four screws of the pump head fig.
