Materials

Standard materials of construction with ASTM designation.Other API material classes are available on request.

The interchangeability advantage

RPH pumps are designed to give "maximum interchangeability" advantage to the customer. A wide range of 52 hydraulics is covered just by 4 sizes of bearing bracket. Thus imparting maximum flexibility for inventory control.

The customer finally has

- Reduced no. of pump parts

- Only 4 sizes of mechanical seal

- Lower operating cost

Design

Fields of applications

(As per API 610 / 10th edition)

RPH is a horizontal, single stage,

radially split pump in back pull out

design with end suction and top

discharge. It has a single entry

enclosed radial impeller.

These pumps are also available with

inducer (on request).

RPH pumps find extensive

applications in

- Refineries

- Petrochemical industries

- Fertilizer industry

- Heavy duty oil and gas services

Operating data

Pump sizes DN 25 to 250 mm

3Capacity Q up to 1500 m /hr.

Head H up to 270 m

Pressure P up to 51 bar(Higher pressure

rating on request)

0 0Temperature t -70 C to 450 C(Higher / Lower temp.

rating on request)

Special features

Finned bearing housing and air cooling with fan allow 0operation of the pump upto 315 C without water

cooling.

Since the seal chamber is designed in full compliance

with API 682; the shaft seal as per API 682 can be fitted

into the seal chamber as a standard.

1 As cast fins and an optional fan0Allow running of the pump up to 315 C without

water cooling. Water cooling option available for

extremely high temperature.

2 Seal chamber

Designed as per API 682 as a standard

3 Volute casing

Double volute for sizes DN 80 mm and above to

minimize radial load and shaft deflection. ASME B

16.5 Class 300 RF flanges as a standard. Other

ratings available on request.

4 Impeller

Designed for low NSS. Inducer option available on

request. Positively locked impeller nut.

6 Casing drain

Ensures complete drain.

8 Casing cover

Cooled or heated as optional arrangement.

9 Rigid and heavy shaft

Ensures minimum shaft deflection as per API 610

Ensures max. seal and bearing life.

10 Bearing bracket

Rugged design to ensure low vibrations. Magnetic

drain plug for a cleaner oil reservoir. Bearing

isolator to enhance bearing life. As cast fins for

convective heat transfer. Triplex bearing

arrangement available as an option for high

suction pressure.

7 Metal to metal fit

Controlled compression SS 316 spiral wound

gasket between casing and casing cover.

5 Impeller nut

Positively locked impeller nut.
