The MX Horizontal Multistage Pump

Hydraulic Coverage (60 Hertz)

BW/IP's Unique Positive Sealing Top/Bottom Interstage Bolting Arrangement

( Why does BW/IP give you standard features such as our unique Positive Sealing Top & Bottom Interstage Bolting and a super robust shaft through the impeller?

It is not normal operation that causes down-time in critical and hazardous duty multistage pump applications, but less controllable items such as system upsets, process changes or abnormal operation that keeps a heavy duty API 610 pump from extended mean-time-between-failure performance...

For this reason a light or medium duty pump SHOULD NOT be applied in most critical or hazardous services.

That is why BW/IP only manufactures a heavy-duty version of our MX Pump. In today's safety and environmentally-conscious climate a medium/light duty multistage pump may not provide the reliability and performance that you require.

Let's look at the facts:

INNOVATIVE MX FEATURES DIFFERENTIAL ADVANTAGES

1. Exceeds API 610 7th Edition Design Standard * More rugged design & testing criteria insure improved reliability, safety, and performance

2. Double Volute Case * Fully balances radial forces over the entire operating range

3. Opposed Impeller Design * Provides complete axial hydraulic balance which remains undisturbed by wear

4. Horizontally Split Case * Permits the rotating element to be balanced & assembled as a unit, complete with wear parts

5. Suction Specific Speed of less than 11,000 for entire MX product range

* Allows the pump to perform over a wider operating range with greater unit reliability

6. Super Robust Shaft as Standard * Reduces shaft deflection which is a major cause of seal and bearing failures

7. Unique Positive Sealing Top/Bottom Interstage Bolting Arrangement

*

*

Reduces the chance of product leakage at the parting flanges — allowing safer operation Eliminates the need to "crown" (a difficult machining operation in most non-OEM shops) the case halves to insure sealing across the complete pressure and temperature range of the pump

8. Stuffingbox Dimensions which exceed proposed API Seal Standards

* *

Can be of assistance in seal standardization programs Accommodates standard double or tandem cartridge seals

9. Hardfaced Center Stage Piece and High Pressure Box Sleeve & Bushing Option

* Hardness differential between the parts reduces galling and erosion

10. Case Sag Boring Option -- whereby the shaft deflection is machined into the case halves

* _

Eliminates rubbing at startup and coast down

11. Dowelled Tongue & Groove Case Wear Rings * Reduces the potential for misalignment and simplifies assembly
