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.
