Technology & Benefits
The revolutionary design and construction reduces the number of moving parts in the pump and creates an extremely low cycle time which results in minimal downtime and maintenance over the lifespan of the pump, substantially reducing cost.
The reliability of the APT pump technology results in a significantly lower Cost of Ownership than traditional Triplex & Quinteplex pumps.
​
Unlike conventional reciprocating plunger pumps, APT pumps use a unique, patented “modified-bellows” design featuring pressure cylinders incorporating internal bellows that are actuated hydraulically. The fluid is introduced into the cylinder when the bellows are collapsed. After the bellows are filled to their measured volume, the fluid is expelled through the discharge valve. The pumping fluid and the hydraulic oil are not co-mingled. The hydraulic fluid is pumped by a multi-cylinder, positive displacement, adjustable-stroke hydraulic pump. The hydraulic pump can be driven by either an electric motor, or a gas or diesel engine.
​
The ATP pump’s prime mover (the electric or diesel motor, the hydraulic pump unit and the cooling fan) can be separated and moved to another location when working in high-risk environments (such as flammable atmosphere) and in locations where noise levels must be reduced to a minimum, or space is limited.
​
Conventional positive displacement pumps generally have three pressure ranges — Low, Medium and High. Each range has its own fluid cylinder and valve arrangement. When a customer needs to change the pressure or volume of his pump, as is often the case in the oilfield, he is forced to change the plunger size and/or the crankshaft speed, which involves shutting down the pump, changing the complete fluid cylinder and/or pump speed. Both of these changes are expensive, and consume considerable non-productive down time. The APT pump has no such limitations and can change pressure and volume instantaneously throughout its whole range.
