Lowers Operating Costs, Enhances Safety

The Clark Reliance Non-Electric Fluid Recovery Pump provides substantial operating economies in the transfer of high temperature liquids such as condensate from a low point, low pressure, or vacuum to an area of higher pressure or elevation.

The non-electric design offers significant advantages including performance reliability in remote areas where electrical service is not readily available. Safety concerns are minimized on applications involving hazardous explosive atmospheres.  

The Fluid Recovery Pump unit can easily be installed to collect condensate or other liquids from single or multiple return lines.

Condensate Management

When condensate leaves the steam trap, it contains approximately 20% of the heat energy transferred in the boiler to generate steam.

Total condensate management prevents:
Excessive blowdown.
Loss of expensive heat energy.
Waste of water treatment chemicals.
High make-up water costs.
Added costs to preheat feedwater.
All too often these problems are just accepted simply because no readily available solution exists.
The Total System Solution

The Clark Reliance Non Electric Pump is specifically designed to remove condensate under all operating conditions and provides the unique opportunity to solve all condensate handling problems.

The pump is a self-contained unit using steam or other pressurized gas as its motive power. There are no electric motors or level switches, simplifying installation and making it ideal for wet or hazardous areas.

One pump design covers all applications from vacuum systems to highly efficient heat exchangers, including general condensate return.

The Clark Reliance Non Electric Pump outperforms more complicated and expensive condensate handling systems. An added benefit is the ability to effectively pump high temperature fluids. Plant maintenance problems caused by leaking mechanical seals and cavitation are eliminated.

Applications
Condensate removal from process vessels and heat exchangers (open system)
Condensate recovery (open system)
Condensate recovery and flash steam recovery (closed system)
Condensate removal from air heaters (closed system)

Benefits

Designed To ASTM Accepted Standards

The Fluid Recovery Pump can be operated by steam, compressed air, or other gas to 125 PSIG. No electrical energy is required, making the pump safe in hazardous environments. Maximum temperature is 400°F. Body construction is of fabricated steel with all stainless steel check valves for pumping liquids of .9 to 1.0 SG. Valve sizes must be specified when ordering .

An all stainless steel, float operated snap acting mechanism has hardened stainless steel valves and seats. There are no external seats or packing to leak.

Note: Actual check valves are specified per application and are required for pump operation.

Sizing Your Fluid Recovery Pump EXAMPLE
1. What is the desired lbs./hr. of fluid to be pumped?  
2. What is the available motive gas or steam pressure? 2800 Ibs./hr. 25 PSIG 15 PSI*
3. What is your total lift or back pressure?    

Total lift and back pressure is the total pressure that the pump will be working against. This includes changes in fluid elevation, check valve cracking pressures, and any minor losses due to the piping system. A one foot change in elevation is equivalent to a .5 PSI back pressure.

Total Lift or Back Pressure = (.5 x Total Feet of Lift) + Minor Losses of Piping

        Vertical lift = 28 ft.     Minor Losses = 1 PSI
   *Total Lift or Back Pressure = (.5 x 28) + 1= 15 PSI

4. With the above specifications and a minimum of a 12-inch filling head, select the pump from the table below. Find 25 PSIG Operating Inlet Pressure.   Then, find 15 PSI Total Lift or Back Pressure. You can see that a 1 inch check valve kit will allow you to achieve the 2800 Ib./hr. pumping rate you desire.

Pump Capacities

In pounds per hour for liquids of 0.9 to 1.0 specific gravity (lower on request), with 12" filling head installed as recommended above pump top. Inlet port 3" N.P.T.; Outlet port 2" N.P.T. Optional ports and check valves available.

For capacities in GPM, multiply Ibs./hr. by .002. For Kg/hr., multiply by .454. For liquid specific gravities below .9, call the factory.
