Everest Super Suckers for De-silting of Sewer Manholes

It will be a skid mounted unit with a High Vacuum Pump Suction System which will create high Vacuum in the pay loader damper / tank wherein the sludge / slurry, perlilte, dust, etc. from the sewer line is collected. The basic principle operation high air flow from the collection tank. This suction pump has got a very high capacity to suck the slurry from large distances and in depth. In super Sucker 4000 suction pump is driven by a diesel engine of nearly 155 / 175 BHP. In order to avoid any slurry to enter into this pump a suitable cyclone separator with in line filters is provided just before this pump with suitable relief valves. Since this suction pump will be sucking high amount of air and also discharging a high amount of air into the atmosphere, therefore, suitable absorptive and reactive type of silencer is provided, the same shall be fitted with inlet and exhaust filters. The whole system will be put inside an acoustic hood in order to reduce the noise level.

The main equipments involved are as under :-

(a) High Vacuum Pump :- This will be tri-lobe type suction pump / Vacuum Blower. It will be a positive displacement type Vacuum Blower. The suction pump will have reduced discharge pulsation making the flow smooth. The noise generated will also be low due to reduced pulsation. The suction pump will have very high pumping capacity of the order of 4000 – 4500 m3/hr.

Cyclone Separator :- The cyclone separator will have a cone design, wherein debris can be entrapped to avoid them to enter inside the Suction pump.

(c) Filters :- There will be in line filters in between the cyclone separator and the suction pump, in order to trap very minute particles to enter inside the Suction pump.

(d) Pressure Relief Valve :- This valve will automatically prevent over suction which can cause engine ( drive system) to overload, thus protecting the blower. A manual valve will also be provided to bypass the suction line and can be operated when relief valves do not operate. A valve will be provided at the lower end of cyclone separator which can be operated after the process is complete.

(e) Acoustic Enclosure :- It is sound proof enclosure to overcome the excessive noise. The whole system with Suction pump, Cyclone separator, filters, pressure relief valve, etc. are enclosed in this enclosure.

(f) Electric Control Panel : It will inside the acoustic enclosure for the starting & stopping the diesel engine and also for controlling the diesel Engine parameters.
