Engineered for continuous-duty boiler feedwater, process water transfer, and desalination pretreatment service
Request Technical SpecificationsEngineered for continuous-duty performance in power generation, petrochemical, and desalination applications
The multistage hydraulic layout delivers a rated output of 750 kW and maximum discharge pressure of 32 bar, engineered for power plant boiler feedwater service where sustained high-pressure operation is required around the clock.
The TP-750 handles flow rates from 120 to 480 m³/h, providing selection flexibility across boiler feedwater, petrochemical process water transfer, and desalination pretreatment duties without changing the pump platform.
Rated for continuous operation at fluid temperatures up to 180 °C, the TP-750 supports demanding thermal power plant and petrochemical process conditions.
Hydraulic efficiency of up to 87% reduces energy consumption over the pump's service life, and a noise level below 78 dB(A) at 1 m contributes to a quieter, safer plant environment.
A 316L stainless steel impeller and duplex stainless steel (ASTM A995) casing provide durable, corrosion-resistant performance, including in seawater-adjacent desalination pretreatment service.
Available in 2 to 6 stages configured per duty point, with a cartridge mechanical seal and oil-lubricated sleeve bearings, allowing duty-point-specific selection for each project.
Every unit is factory-tested to KS B 6301 before shipment, including a hydrostatic test at 48 bar held for 30 minutes, and ships with its individual test certificate.
In 2024, a 500 MW coal-fired power plant replaced six boiler feedwater pumps with TP-750 units, all of which have operated without unplanned downtime since commissioning; other TP-750 units operate in petrochemical process water transfer at 160 °C and in desalination pretreatment systems.

Real-world performance across power generation, petrochemical, and desalination operations
Thermal power — boiler feedwater: In 2024, a 500 MW coal-fired power plant replaced six boiler feedwater pumps with TP-750 units. All six units have operated without unplanned downtime since commissioning, demonstrating the reliability of the TP-750's multistage high-pressure design under sustained, round-the-clock power plant duty.
Petrochemical — process water transfer: A petrochemical complex operates TP-750 pumps in continuous duty for process water transfer at 160 °C, well within the pump's 180 °C rating, confirming its high-temperature capability in demanding process environments.
Desalination — pretreatment: TP-750 units supply pretreatment systems at a seawater desalination plant, where the 316L stainless steel impeller provides corrosion resistance in seawater-adjacent service.
These installations form part of Meridian Pumps' cumulative delivery of 1,240 pump units, serving 15 domestic power plants and customers in 9 countries — a track record backed by ISO 9001 and ISO 14001 certification and, since 2023, CE certification for the European market.
