API 610 Process Pumps from Shin Nippon Machinery
Heavy duty API 610 pumps for refineries, petrochemical plants, power plants and LNG, supplied and serviced in North America by PPS.
Overhung OH2, OH3 and OH4 (model NSI)
Centerline supported single stage pumps for high temperature service. Forced air cooling is standard to 250 C; a water jacket bearing housing is used above that.
| Maximum flow | 1,500 m3/h |
|---|---|
| Maximum differential head | 400 m |
| Maximum temperature | 400 C |
| Pressure rating | 4 MPa |
Between bearings BB1 (models RTH and SD-S)
Axially split, double volute pumps. RTH is two-stage with centerline support for low NPSH, large capacity and medium pressure. SD-S is single stage, double suction, for large capacity and low NPSH.
Between bearings BB2 (model HDV)
Radially split, single stage, double suction, double volute pump with centerline support for large capacity, low NPSH and high temperature. Overhaul without removing the main piping or driver.
Between bearings BB3 (models HTB and MTB)
Axially split multistage pumps for high pressure and large capacity, including boiler feed water. Opposed impellers balance thrust; HTBD has a double suction first stage.
BB5 barrel pumps (model BTBF)
Radially split, multistage, double casing barrel pumps with diffuser guide vanes and centerline support, for high pressure, high temperature and high speed service such as boiler feed water and HP ethylene.
| Maximum flow | 1,100 m3/h |
|---|---|
| Discharge pressure | Up to 2500# flange rating |
| Maximum temperature | 400 C |
| Maximum speed | 6,000 rpm |
| Outer casing | Forged steel, metal-to-metal fit with controlled compression gasket |
Vertically suspended VS1, VS6 (model CZ) and VS4 (model SIW)
CZ is a double casing multistage vertical diffuser pump (VS6), or a submerged VS1 without the outer casing, suited to low temperature and low NPSH services such as propane and LNG. SIW is a line shaft vertical sump pump (VS4), with a seal-less SIWN version and a semi-open SIWO version for pits.
API 610 pump questions
Which API 610 pump types does Shin Nippon Machinery build?
Overhung OH2, OH3 and OH4; between bearings BB1, BB2, BB3 and BB5; and vertically suspended VS1, VS4 and VS6.
Do the seal chambers fit standard API 682 seals?
Yes. Seal chamber dimensions conform to API 682 and API 610, and dual seals can be installed.
Can you replace an existing API 610 pump from another OEM?
Yes. Send the data sheet and the existing nozzle and baseplate dimensions; we propose a Shin Nippon Machinery replacement and the scope to fit it.
Send the API 610 data sheet. We return a selection, curve and price.
