TELESCOPIC VALVES
Mod. EM37

Application	Evacuation of floating material or sludge
Characteristics	A telescopic adjustable tube is fitted into a lower pipe.
Operation	The liquid flows into the lower part and flows out through the telescopic tube thanks to the head effect. The higher is the head, the larger is the flow rate.
Material	The tube is made of stainless steel
Tube Diameter	From 80 to 600 mm.
Optional	Motorized control

The following technical data are required to make a quotation:

Per quotare una valvola telescopica occorre conoscere i seguenti dati:

1.1	Flow rate to be evacuated	: m3/h
1.2	Stroke of the tube	: mm.
1.3	Pipe diameter (if already sized)	: DN o mm.
1.4	Pipe materialo
1.5	Drive handwheel requested position

Moreover you should specify:
• whether the telescopic valve shall be motorized
• if an emergency by-pass valve (quick opening type) will be installed at the plant

CLEANING BRUSH FOR CLARIFIERS
Mod. EM84

Application	Cleaning of the clarifiers circular ditches.
Characteristics	This accessory mainly consists of a motorized rotary brush and a lifting-adjustment unit.
Operation	The brush is placed adherent to a side of the ditch and is started.
Material	Galvanized or stainless steel.

To be able to make a quotation for a cleaning brush we need a drawing of the machine and ditch to clean, with the following data:

1.1	Ditch width	: m.
1.2	Ditch height	: m.
1.3	Position to fix the rotary brush group	: m.

AIR LIFT
Mod. EM77

Application	Lifting of liquids even when containing a considerable amount of solid material.
Characteristics	The equipment is made of a lifting pipe, a lower suction unit and a top drain unit.
Material	Galvanized or stainless steel

The following technical data are required to make a quotation:

1.1	Required capacity	: m3/h
1.2	Water level	: m.
1.3	ain height, above the water level	: m.

There is a lower head consisting of a central pipe and external chamber for the air distribution. A series of calibrated holes homogeneously diffuse the air inside the lifting pipe. The upper head is made of a tank with cover which receives the water and air coming from the tank bottom. The aim of the upper head is the separation of air from water which is discharged through the top.

OIL SKIMMER PIPE
Mod. EM66

Application	Evacuation of the floating material.
Characteristics	The equipment is made of a rotary slotted pipe and a regulation unit.
Material	Galvanized or stainless steel
Optional	Motorized control

Description of operation

By turning the control handwheel in a clockwise or counterclockwise direction, a bronze nut screw on which a screw is engaged rotates too.
The screw moves, upwards or downwards, together with a rack which is integral to the screw.
The rack is engaged on a crown wheel which makes the oil skimmer pipe rotate.

The scraper bridge is finishing his return run with the skimming blade down and conveys the floating material towards the oil skimmer.
When the skimming blade gets next to the oil skimmer, the pipe is rotated till the longitudinal slots are partially submerged and the floating material flows out.
This operation can be repeated after a certain number of operation cycles or the oil skimmer pipe position can be adjusted to achieve a constant minimum, but sufficient, evacuation of the floating material.
This gives rise to a surface calling effect which, also increased by the skimming blade approach, collects the floating material and conveys it out.

The following data are required to make a quotation:

1.1	Tank width	: m3/h
1.2	Pipe diameter	: m.
1.3	Material

Moreover you should specify whether the oil skimmer pipe shall be manual or motorized.
