Electrical characteristics of a solenoid coil

TL;DR Summary

Electrical characteristics of a solenoid coil(voltage rating)

I have a fuel pump consisting of a solenoid coil. I have tested the fuel pump at 12V supply. The pump actuates at 20% duty cycle(200Hz frequency) and draws a current of 1.7A. When I increase the supply voltage to 24V it actuates at 7% duty cycle(200Hz Frequency), drawing a current of 0.6A. How can I verify for what voltage is the coil rated without damaging it? It is not possible to open the fuel pump and check the solenoid coil. I do not have any datasheet. Fuel pump P/N: HQ A2C16376700

The pump actuates at minimum 20% duty cycle and above for 12V supply. Is there any way that I can check voltage rating(If the coil can withstand 24V?). Since at 24V the pump actuates at 7% duty cycle which is my requirement.

 

[Baluncore]

You must limit the heat generated in the coil.
Double the voltage will double the current, which will generate four times the heat per unit time. The duty cycle goes from 20% to 7%, which is one third of the time on.
On 24V, that is 1/3 * 4 = 133% of the 12V design heat.

How can I verify that the coil can withstand 24V without causing any damage to it?

How can I verify that the coil can withstand 24V without causing any damage to it?

You cannot.
The coil will have been designed for a particular application.
What is the new application ?

 

[core7916]

In my application I require the pump to open at less duty cycle. While testing I observed that when the supply voltage was increased to 24V the pump actuated at lesser duty cycle.

Is there any method by which i can determine the rated voltage of a solenoid coil by using the coil resistance?

You have not described the circuit you use to power the solenoid.
Do you control the duty cycle with a switching supply, or does the pump change duty cycle based on the continuous voltage applied?

No.
Different solenoids are wound with different size wire, for different magnetic field strengths.

PWM is given from a function generator.

It seems like an overheating fuel pump would be a really bad thing.

The OP has a history here at PF of posting questions about dangerous activities, so this thread is now done and the OP is on a temporary vacation from PF.
