TLV GP5C Compact Mechanical Pump for Condensate Recovery

TLV GP5C compact mechanical pump for condensate removal and recovery. This PowerTrap operates with an extremely low filling head and handles high-temperature condensate without cavitation. Since it requires no electric power or additional level controls, it is intrinsically safe.

Features

  1. Handles high-temperature condensate without cavitation.
  2. No electric power or additional level controls required, hence INTRINSICALLY SAFE.
  3. Pump will operate with an extremely low filling head (min. 155 mm).
  4. Linear inlet/outlet greatly reduces installation time.
  5. Easy, inline access to internal parts simplifies cleaning and reduces maintenance costs.
  6. High-quality stainless steel internals and hardened working surfaces ensure reliability.
  7. Compact design permits installation in a limited space.

General Description

TLV GP5C general description Install properly and DO NOT use this product outside the recommended operating pressure, temperature and other specification ranges. Improper use may result in such hazards as damage to the product or malfunctions which may lead to serious accidents.

Application

The PowerTrap is used to discharge liquid from low-pressure areas to high-pressure areas, or from lower to higher elevations. The PowerTrap GP5C has an integrated pumping function that can eliminate and pump out condensate even if condensate cannot be discharged due to very low supply steam pressure because of reduced load in the steam-using equipment ('stall'). The GP5C can also discharge the accumulated condensate when the steam-using equipment stops operation, and prevent water hammer when it re-starts operation.

Type of SystemClosed SystemOpen System
OverviewThere is no piping system that opens to the atmosphere and the condensate of 100 °C (212 °F) or less can be recovered.There is a piping system that opens to the atmosphere and the condensate of 100 °C (212 °F) or more can be recovered.
FeaturesCollection of condensate from multiple equipment. No venting of flash steam possible. Small reservoir compared to the open system. Use with vacuum equipment possible.Can be used where trap is lower than receiver, such as equipment situated near grade (providing there is sufficient differential pressure).
NotesOnly one piece of equipment possible per system. Equipment has minimum height requirement.Separate steam trap required for each piece of equipment. Requires venting pipe to discharge flash steam to atmosphere.

Operation

WARNING

Take measures to prevent people from coming into direct contact with product outlets. Failure to do so may result in burns or other injury from the discharge of fluids.

  1. When condensate flows from the condensate inlet pipe through the inlet check valve into the body of the unit, the air in the body escapes through the exhaust valve and the float rises.
  2. When the float rises to its high level, the push rod on the snap-action unit rises quickly, simultaneously closing the exhaust valve and opening the intake (motive medium) valve. The pressure supplied by the motive medium causes the internal pressure in the unit to become greater than the back pressure, forcing the condensate out.
  3. As a result of the condensate in the unit being discharged, the water level in the unit drops and the float descends. The exhaust valve opens, the intake valve closes, and the cycle repeats.

Installation and Open System Piping

WARNING

Use hoisting equipment for heavy objects (weighing approximately 20 kg or more). Failure to do so may result in back strain or other injury if the object should fall.

TLV GP5C open system piping example

  • Motive Medium Supply Pipe: The diameters of the motive medium supply pipe and of the valve on the motive medium supply pipe should be at least 15 mm.
  • Exhaust Pipe/Tube: The exhaust pipe/tube should be connected to the upper part of the condensate receiver. The exhaust pipe/tube should be shorter than 3 m, and with an inner diameter of 8 mm or greater.
  • Inlet and Outlet Piping: Install a condensate inlet pipe to help condensate flow into the PowerTrap by gravity. The condensate outlet pipe diameter should be at least 25 mm (1 in).

Sizing the Condensate Receiver

Be sure to select a receiver of the correct size. The filling head represents the distance from the bottom of the PowerTrap to the bottom of the receiver. Filling heads lower than the minimum filling head of 155 mm must not be used.

The product should be inclined no more than 3° front-to-back and left-to-right. Ensure the product is horizontal by checking the machined surface of the cover top.

Disassembly/Reassembly

DANGER

NEVER apply direct heat to the float. The float may explode due to increased internal pressure, causing accidents leading to serious injury or damage to property and equipment.

WARNING

When disassembling or removing the product, wait until the internal pressure equals atmospheric pressure and the surface of the product has cooled to room temperature. Disassembling or removing the product when it is hot or under pressure may lead to discharge of fluids, causing burns, other injuries or damage.
