In many cases, the price you can find online is about what a service company will pay at a local wholesaler.
If you give a markup of 1.40 times, the retail should be about $1,450.00 x 1.40 = $2,030.00, which is a profit of $580.00.
If you allow $150.00 per hour, the labor should be about $150.00 x 3 = $450.00.
So, the total will be about $2,030.00 + $450.00 = $2,480.00.
The labor is what it is.
The retail price of the pump is probably somewhat negotiable.
Maybe get some other proposals to see where other companies are for the total.
Maybe send a counterproposal for a total price you think is more reasonable.
The company’s break even will probably be about $1,450.00 + 450.00 = $1,900.00.
They need to make some profit on retail items like any other store selling products.
Part of the cost is to ensure that they will be ready, willing and able to service the pump under any issues like a warranty claim.
$2,400.00 total would give them about $500.00 profit, which is probably plenty, but they can pass at any offer less than their initial price.
