Pentaflo Hydro Pvt Ltd Kalkaji, Delhi

» Horizontal S-type turbine equipped with diagonal distributor and S-type draft tube. » The shaft is conducted through the elbow to the generator. » Draft tubes can be designed with one or two elbows.

Pelton turbine is an impulse turbine for high heads. Our Pelton Turbines guarantee highest operating efficiency and reliability. » We manufacture Horizontal Shaft Pelton turbine with 1-3 jets arrangement. » For vertical shaft arrangement 4-6 jets are required. » Runner in Stainless steel is integrally cast. » Micro range Pelton, buckets are bolted to hub. » For Horizontal Shaft arrangement bearings are roller type grease lubricated. » Regulation - ON/OFF Type and Regulating Type Applications » Pelton Turbines are used for water energy production in areas with high hydraulic head and low water flow. » Pelton Turbine is the most efficient in case of inlet water with high pressure.    

» pentaflo manufactures micro hydro turbines of all types to meet the demands of remote mountain residents/national park/rural village/school/military camp/outdoor camp etc. » depending on site parameters we manufacture cross flow, peltric, turgo and propeller type turbines. » package units are also provided which comprise of turbine with synchronous generator, electronic load controller to maintain proper voltage. .

Pentaflo design and manufacture hydraulic hoists for fixed wheel roller vertical gates for the main canal and for the Penstock inlet gates located in the forebay. The hydraulic hoist comprise of a precision designed hydraulic cylinder and an oil pumping unit. The cylinder road is either attached to the gate directly or in case of canal system to the counter weight which in turn is fastened to the gate through steel wire rope.In case of main canal gates which is a bypass to the power plant channel and is required to open automatically in the event of plant shut down condition, the counter weight is released to fall by the hydraulic cylinder thereby opening the gates.

The core of any modern hydro plant is high efficiency and automated control system. Pentaflo offers digital governing system having auto- synchronizing facility for the plant. The switch cabinet is a kind of electrical equipment, outer line firstly enter the master control, switch inside the cabinet and then enter the sub-control switch. Each shunt is set according to their needs. Pentaflo provides complete electrical equipment for the power house which comprises of switchgears and controls with automated switching sequence. Pentaflo also provides remote based system for unattended operation.

Unlike most water turbines which have axial or radial flows, in Cross flow Turbine the water passes through the turbines transversely, or across the turbine blades. The cross flow turbine is a low speed machine well suited for locations with a low head but high flow. » We have developed significantly improved cross flow turbine incorporating radial adjustable shutter plate thereby giving flat efficiency over quite good range of discharges. » Runners are either of Stainless Steel or mild steel. » We provide self closing type inlet butterfly valve shall close automatically due to provision of dead weight on the lever arm. » We provide speed increasing gear box between turbine and generator. Applications » Dam SHPP » Run of river SHPP » SHPP in drinking water systems » SHPP for electrification of remote areas.  

Features   » Pentaflo's butterfly valves are able to open and close under equalized water pressure on the disc sides as well as to close at full Turbine discharge. » In addition, emergency closure valves shall close automatically in case of penstock rupture. The opening is done by means of one standard servomotor. » We manufacture turbine inlet butterfly valve double off set type (double eccentric). » We offer hydraulic operator with the provision of counter weight for self-closing in the event of any fault. » The valves are fabricated or made from cast steel. » Size ranges from ø 150mm to 2500mm.
