Spirax Sarco MFP14-PPU is an open combined condensate recovery pump set comprising a carbon steel receiver, a ductile iron mechanical pump and stainless steel check valves. It is available in single-, twin- or triple-pump configurations and can be driven by steam or compressed air. Its non-pressurized open design effectively reduces backpressure on upstream steam traps, making it suitable for centralized condensate recovery stations serving multiple items of equipment. A PSHE TYPE2 flash steam recovery unit is also available as an option for applications requiring simultaneous condensate recovery and flash steam handling.

Application scenarios
Centralized Condensate Recovery Station for Multiple Equipment Items
Used to collect condensate discharged from multiple steam-using heat-transfer equipment items or upstream steam traps, and to recover it centrally through an open, non-pressurized receiver tank and combined pump set. The open design helps reduce backpressure on upstream steam traps and ensures normal operation of the upstream process.
Condensate Recovery System with Flash Steam Recovery Unit
Used where flash steam must be handled simultaneously during condensate recovery. An optional PSHE TYPE2 flash steam recovery unit can be fitted to work with the MFP14 open combined pump set for condensate recovery and flash steam handling.
Selection points
Open, Non-Pressurized Receiver Tank Design
The receiver tank uses an open, non-pressurized design to minimize backpressure on upstream steam traps, prevent impaired drainage and ensure normal operation of the upstream process.
Single- to Three-Pump Combination Configurations
The pump set is available in single-, twin- or three-pump configurations, making it possible to select a configuration according to condensate recovery requirements.
Multiple Motive Medium Options
The pump set can use saturated steam, compressed air or another stable and safe gas as the motive medium.
Optional Flash Steam Recovery Function
The pump set can be fitted with an optional PSHE TYPE2 flash steam recovery unit to provide flash steam recovery.
Two Types of External Connection Standards
External connections can be specified with PN16 flanges and BSP threads, or ANSI 150 flanges and NPT threads.
Installation & maintenance notes
Keep the Open Receiver Tank Vent Unobstructed
During installation, keep the open receiver tank connected to the atmosphere and ensure that the vent path remains unobstructed to prevent pressure from developing in the tank and increasing backpressure on upstream steam traps.
Limit Saturated Steam Motive Pressure
When saturated steam is used as the motive medium, the inlet pressure must not exceed 13.8 bar g.
FAQ
How does the MFP14 open combined pump set work, and how does it recover condensate?
The MFP14 open combined pump set integrates an automatic pump, open receiver tank and necessary accessories on a single frame. It uses steam, compressed air or another safe gas as the motive medium to drive the pump, collecting and returning condensate generated by upstream steam traps to the system. The open receiver tank is non-pressurized, keeping upstream backpressure low to maintain unobstructed steam trap drainage and stable operation of the upstream process.
What are the main differences and applicable scenarios for single-, twin- and three-pump sets during selection?
Different numbers of pumps indicate the parallel pumping capacity and meet condensate handling requirements for different processes. Refer to the selection table and associated parameters for the specific model, connection sizes and recovery capacity to determine the configuration that best matches the site operating conditions.
What technical advantages does the PSHE TYPE2 combination with flash steam recovery offer for condensate recovery?
The flash steam recovery capability provided by PSHE TYPE2, together with the cooling water circuit design, helps improve overall heat recovery efficiency and is suitable for applications requiring additional heat recovery. Refer to the listed combination model and parameters for the specific capacity and cooling water requirements.
What are the limits on the maximum motive medium and pressure of the system?
The maximum motive pressure is 13.8 bar g for saturated steam, or the equivalent pressure for air or another safe gas. The receiver tank is open and non-pressurized. Refer to the TIS for the limitations of specific components according to the model.
What connection and safety points require particular attention during installation and maintenance?
The overflow outlet and air vent must be connected to a safe location. External connections can be specified with PN16 flanges (BSP threads) or ANSI 150 flanges (NPT threads). Installation and maintenance must follow the installation and maintenance guide supplied with the product to ensure normal operation of upstream steam traps and stable backpressure.
