Fax: 06 9343924 www.etatronds.com CONFORMITY DECLARATION We declare under our responsibility that metering pumps and the drags of this instruction and maintenance manual are in conformity of the 89/392 Machine Guideline and successive modifications, following the EEC 91/368, 93/44 and 93/68 and of the regulation UNI EN 292/2, of 11/92 and CEI EN 60204 - 1 of 9/93.
- Page 3 INTRODUCTION Dear Customer We thank you for choosing this product and recommend you read this manual carefully before starting installing the dosing pump. Please abide by the technical indications and safety rules herein specified. ▲ ATTENTION! Installing the dosing pump in an environment with fumes and high humidity is not recommended as the alum alloy reducer body and motor, even though they have a finish coat, may be affected, unlike the head made of stainless steel or plastic, which ensures full compability.

- Page 8 OPERATING CONDITIONS Actual capacity depends on viscosity, specific weight of pumped liquid and plant's load loss. Capacity and pressure values reported in the tables are obtained under operating conditions with steady pressure, water at 15°C and pump installed at 30 cm above water level. Actual capacity depends on viscosity, specific weight of pumped liquid and plant’s load loss.
- Page 9 BLOCK REMOVAL Before installing the pump, make sure to remove all protective caps located on the suction inlets and the valve delivery system. PUMP INSTALLATION Allow enough room (operation areas) to check and disassemble the pump, particularly on the hydraulic side (pumping head) and next to the adjustment knob.

- Page 13 The type of oil recommended for the pump body or gear box should have the following requirements: high viscosity index and cold flow rate. Internationally defined as: SAE 140 with 23° E viscosity (about 160 mPa/s) This type of oil is available from different manufacturers: Esso - Gear Oil GX 85W 140 Shell - Spirax HD 85W 140 IP - Pontiax HD 85W 140...
- Page 14 MOTOR TO POWER SUPPLY CONNECTION DIAGRAM ACTIVATING THE PUMP 14.1 OPERATION DESCRIPTION The operations required before activating the pump include: Check the oil indicator detects the oil in the pump body. Check the motor rotates as indicated by the arrow on the fan cover. Verify dosed liquid is not solidified or frozen in the pipes.
- Page 15 16.2 PUMP CONTROL WITH A PROXIMITY INDUCTIVE SENSOR The proximity inductive sensor can be installed on the dosing pump to check the number of pumping cycles. Every pumping cycle – i.e. one turn of the cam shaft – is matched with an impulse transmitted by the proximity inductive sensor.

Components to be checked Drive Head Valve assembly Motor Maintenance interval Gaskets Piston Plastic Metal Absorptions Hours Biannual Replacement Yearly The "DRAWINGS AND TABLES" manual indicates the symbols corresponding to the parts subject to wear which require frequent maintenance.
- Page 17 “PTFE” GASKET PACK REPLACEMENT AND ADJUSTMENT 20.1 GASKET PACK REPLACEMENT (head with execution 21) After the maintenance procedure is complete, proceed as follows: Disconnect the pumping head 1 from the system and lantern of the dosing pump. Clean the pumping head to ensure the operator can safely handle the component.
