SEWAGE EJECTORS


INTRODUCTION

Tuke and Bell is one of the UK's leading manufacturers of sewage purification equipment with ninety years experience in design and production.

Investment in the most advanced technology and the latest computer aided design systems facilitate the production of the highest quality equipment, serving the needs of both the water industry and domestic customers.

UNIT LIFT AND FORCE EJECTOR

Unit Lift and Force Ejector

CAPACITIES FROM 0.61 TO 2.27 LITRES/SEC AND 30M HEAD

The Tuke and Bell 'Unit Lift and Force' ejector, is one of the company's most successful products. Well over 3,000 have been supplied throughout the world. This system is ideal where a relatively small volume of crude sewage is required to be pumped.

Conscious of the increasing necessity for economy in installations of this kind, Tuke and Bell have adopted the 'Lift and Force' principle to a compact and simple form in which the ejector body, air container, motor and compressor are assembled as a single unit.

Discharge capacities range from 0.61 to 2.27 litres per second. Suction and delivery connections are 100m bore throughout, having the capability of passing unscreened sewage.

The Unit ejector is the ideal lifting plant for raising crude sewage to small disposal schemes. The rate of discharge can be adjusted within a very wide range, whilst leaving the sewage passage ways completely unrestricted.

As with our other ejectors, the 'Unit' is usually installed in duplicate. However, a single arrangement can be provided with duplicate compressor/ motor sets to give duty and standby facilities.

Air pipes on both the suction and delivery side of the compressors are inter-connected so that with this system the ejector may be operated by either compressor, leaving the standby set available for use in an emergency. A Tuke and Bell automatic changeover device is fitted as standard.

ADVANTAGES

  • A considerable saving in both material and labour
  • Can pass unscreened sewage
  • Practically no maintenance

ELECTROMATIC SEWAGE EJECTOR

Electromatic Compressors / Air Receiver

CAPACITIES UP TO 9 LITRES/SEC AND 30M HEAD

The Electromatic gravity-filled ejector adds a new dimension to sewage lifting, improving efficiency and reliability without additional costs.

The equipment may be supplied as either a single or duplicate installation. It has been designed by Tuke and Bell to eliminate the conventional float and associated valve gear, and hence reduce maintenance problems. The design is a simple but highly effective combination of pneumatics and electronics. Virtually no maintenance is required and the only lubrication is the topping-up of the compressor and occasional greasing of the motor bearings.

OPERATION

Electromatic Ejector

Sewage flows into the ejector body by gravity and when the level reaches the combined initiating probe/air supply pipe, an air control valve operates, allowing pressurised air into the body. expelling the liquid into the rising main.

ADVANTAGES

  • No float
  • No float spindle gland - reduced leakage
  • No moving parts in contact with sewage
  • Single control panel to minimum IP.54 rating
  • Ejector cycle controlled pneumatically and electrically
  • Practically no maintenance
  • Grease formations within ejector body minimised
  • We can easily convert ejectors supplied by other
    manufacturers, to our system

DIRECTOMATIC SEWAGE EJECTOR

Directomatic Ejector

CAPACITIES UP TO 9 LITRES/SEC AND 12M HEAD

The Directomatic gravity filled ejector eliminates the need for a compressor and air receiver housing, and is a substantial improvement on established methods of sewage lifting.

The equipment may be supplied as either a single or duplicate installation.

It has been designed by Tuke and Bell to eliminate the conventional float and associated valve gear, and hence reduce maintenance problems. The design is a simple but effective combination of pneumatics and electronics. Virtually no maintenance is required and the only lubrication is the topping-up of the compressor and occasional greasing of the motor bearings.

OPERATION

The sewage flows into the ejector body by gravity and when the level reaches the combined initiating probe/air supply pipe, an air control valve operates allowing air direct from the compressor into the body, thus expelling the liquid into the rising main.

ADVANTAGES

  • Efficient and reliable
  • Eliminates need for air receiver
  • Eliminates need for above ground compressor house
  • No float
  • No float spindle gland - reduced leakage
  • No moving parts in contact with sewage
  • Single control panel to minimum IP.54 rating
  • Ejector cycle controlled pneumatically and electrically
  • Practically no maintenance
  • Grease formations within ejector body minimised
