TD Vertical Multi-Stage Pumps

Introduction:

TD is vertical, multistage, single suction, centrifugal pump. It is used to pump the medium flammable, explosive, volatile, poisonous, high-temperature, such as methane, ethane propane, tthylene, propylene, as well as other liquefied gas and light hydrocarbon.

Designing according to API 610 standard.

Performance:

Applications:

Petrocemical industry

Low-temperature engineering

Refinery

Pipeline Pressured

Power plant

Off-shore oil extraction platform

Structural Features:

TD is vertical cartridge multistage centrifugal pump, the intergrated structure is desinged according to API610. It is highly reliable and well interchanged. The first-stage impeller which is suction impeller locates at the lowest end of pump. Which can satisfy the critical requirements of NPSH by equipment.

The balance devices is installed in the middle of pump, 95% of the aixal force is balanced by balance device which also effects as center support. A diagonal contacting ball bearing can balance the residual axial frce. The bearing is lubracating by oil and equipped with independent internal circulation, self-lubracating system and oil level control system. The bearing operated on a good condition so that its lifetime is long. The length of the case outside and the assembly depth of pump are decided by the requiremnet of NPSH by equipment. When the pump assembly depth is up to certain degress, option the middle supporting constructre.

Morn than 10 kinds of material available, including 20g, 16Mn, 304, 304L, 316, 316L, 904, CDMCu etc.

The seal type is available for single and double-end and tandem mechanical seal. It also be equipped with cooling, flushing, heating and seal liquid circulation system.

The pump ratates CCW viewing from driving end.
