Application Notes

Here's how some of our customers used this product.

Testing Hydraulic Pumps in the Field

The Background: Our customer is a heavy equipment service center that needs a way to test the hydraulic pumps on the equipment they service to ensure the pumps are capable of creating the flow and the pressure that is required for proper operation of the equipment.

The Problem: Our customer is a large company with many field technicians, each of whom requires a means to test the pumps. With so many units needed, a major concern for the company is cost. As the units will used in the field, durability is another important consideration.

The Solution: The Flo-tech PFM6 is highly regarded as a durable unit at a reasonable price. We were able to cost effectively update our customer’s entire service fleet.
