Pressured Power Pump Unit

In these days of energy conservation hot condensate is too valuable to be lost as it contains more than 25% of heat used in creating steam. Also it is distilled water making excellent feed water for boilers. UKL Pressure Power Pumps are pumps which are used to pump condensate to the desired location and are cheaper to operate against electrically operated pumps which require special impellers to avoid risk of cavitations by condensate and temperature limits of condensate to be handled.

The UPPPU is a skid mounted Assembly. The receiver collects the condensate from various points. The condensate flows through a Uni directional Disc Check Valve (DCV) to the pump section. The Float assembly, inside the pump section, rises with the level of the condensate and at a predetermined level snaps a valve open to let in Steam, while simultaneously a vent valve gets closed. The steam pushes the condensate out through the outlet DCV which too is unidirectional leading the condensate out to the desired point.

Once the pumping is done the level of condensate falls and the float drops down automatically closing the steam valve and opening the vent to vent out the accumulated steam and allow the fresh condensate to enter and begin the next cycle. This is a maintenance free pump, functions as long as there is condensate coming to the pump. Provided as a complete skid mounted unit, with valves, strainers, DCV, Condensate flow meter etc.

Sizes 40, 50, 80 x 50 and Duplex.

UKL condensate recovery system can be used with motive as Steam or Compressed Air.

Available in Carbon Steel Insulation can be provided as optional.

1. What is a pressure powered pumping unit?

It is a mechanical pump, which uses either steam or compressed air as motive to discharge the hot condensate up to the desired elevated location. Most of the times, the desired location is the Boiler feedwater tank, directly or through a deaerator head.

Limitations
Design pressure :- 10.54 kg/cm2
Operating pressure :- 7 kg/cm2
Design temperature :- 185 Deg C
Discharge elevation :- 70 meters from the ground level(equivalent to a 21-floor building)
Discharge capacity :- 12 TPH with a single pump, no limit with multiple pumps in parallel.
Motive pressure :- 3.0 kg/cm2 (min) and 6.00 kg/cm2(max)

2. How does it work?

It is a mechanical pump consisting of a body shell, into which condensation flows with a positive pressure. The body contains a float mechanism, which operates a set of changeover valves, allowing the transfer of the liquid to a higher elevation or pressure. The pump can be operated by steam, compressed air or gas.
1. Condensate flows into the pump through an inlet check valve lifting a float.
2. At the upper limit it opens the supply valve, allowing the motive steam or compressed air to enter in the pump body.
3. The pressure in the pump builds up just enough to overcome back pressure.
4. The pressurized condensate opens the outlet check valve and the discharge starts.
5. When the float reaches the minimum lower level it closes the steam or compressed air supply valve and opens the vent, allowing the condensate to fill the pump again.

3. What are the different sizes?

Single unit - Inlet 40NB and outlet 40NB
Single unit - Inlet 50NB and outlet 50NB
Single unit - Inlet 80NB and outlet 80NB
Double unit - Inlet 80NB and outlet 80NB

4. Does it come with a storage tank?

Each pump comes with a dedicated storage tank and all the components are skid mounted.

5. How are the connections to be done at site?

It has plug and play feature. Only the condensate inlet and outlet lines are required to be fabricated at site.
As per the drawing already submitted by UKL, customers can layout the necessary pipelines prior to the receipt of the pump at site.

6. Is it necessary to dig a pit for the installation of condensate pump?

No,it is not recommended to install the pump below the ground level. However, seldomly in few cases when the condensate pressure is very low(below 0.20 kg/cm2(g)), then a need may arise to install the condensate pump below the ground level. In such cases, it is strongly advised to consult UKL for the proper installation of pump
