Selecting a pump for high temperature requriement

[mech_cool]

Hi All,

I want to select a pump for high temperature liquid with following data/parameters:

Data & Parameters
Flow Rate – Approx. 10 lpm
Liquid Temperature – 300 C
Pressure loss in circuit – 0.4 bar

Liquid Data
Viscosity – 4 cP
Density – 1.90 g/cm3

The application is in solar cookstove where a liquid will store thermal energy and circulate the liquid into the system. I would appreciate your help if you can suggest a compact and low weight pump for above requirement.

For selecting a pump many parameters are required as input such as :
Flow
Head
Sp.gr.
Viscosity
NPSHa
Vapour pressure
Suction Pressure
and solid contents

In absence of above parameters no selection is possible.
Usually OH2 pump can work upto temperature of 450degC.


A well phrased question has answers in itself!!!
