A Dead Ender Pump Can Speed Up Anchor Placement at Concrete Plants
Every piece of reinforced concrete is fitted with at least two anchorage sets, on either end of the stressed concrete. One end is the live end – the side where post-tensioning crews will install the anchor in the field. The other end is the dead end, and here the anchor set is installed at the concrete plant.
Dead ender pumps are a necessary part of this process, enabling concrete plant crews to install dead end anchor sets quickly, reliably, and efficiently. With the right dead ender pump available to your crews, they will have a major speed and productivity advantage as they tension thousands of dead ends every day.
What’s the Difference Between Dead Ender Pumps and Other Hydraulic Pumps?
Installing tensioning anchor sets can be done with most hydraulic pumps, as the process is not all that esoteric. However, pumps specifically designed for dead ending come with one significant advantage – the dump valve.
In hydraulic and pneumatic systems, the dump valve allows for automatic and immediate pressure resetting following anchor placement. One of the most popular pumps available for dead ending (the PE552) offers advance return, so it holds pressure until the motor is shut off and then immediately releases.
Without a dump valve in place, the valve must be manually manipulated between every tensioning cycle. While this only means a few extra seconds per cycle, tensioning crews are expected to handle hundreds, if not thousands of dead end anchor sets every day. Saving a few seconds per cycle adds up to major productivity and cost-saving bonuses for the concrete plant.
What Other Applications are Dead Ender Pumps Suited For?
The PE552 is built on Power Team’s versatile PE55 model, which can be used in a wide variety of applications. In addition to serving as an effective dead ender pump, the PE55 can also be used in the following roles:
Torque wrenches
The PE55 can be used to supply power to torque wrenches, as it allows operators to set the desired pressure level precisely. With precise pressure setting, the PE55 supports safe, reliable torquing for large industrial fasteners.
Spreaders
The PE55 is also a common choice for spreading applications, where it can supply the power needed for extreme spreading force. Hydraulic spreaders are frequently used in rescue operations, where they can easily rip pieces of metal apart. They’re also useful in the oil and gas industry, where they can be used to spread flanges apart for field repair or replacement.
Foundation repair
The PE55 is also seen in foundation repair applications, where the pump can be used for lifting or slabjacking purposes. It’s particularly useful in concrete or steel piering applications, where the PE55 can supply the lifting power needed to drive the piers into the surrounding earth.
A Few Features to Look For in Your Dead Ender Pump
Aside from a dump valve, which should be the primary feature tensioning crews target in their pump, there are additional features that can improve performance and reliability. Some of those features include:
Expanded oil reservoir
The PE552 can be fitted with an expanded oil reservoir up to 10 gallons in size, for additional power supplying.
Lightweight build
The PE552 comes in a lightweight design that makes it more portable than most other hydraulic pumps. In fact, the PE55 base model offers the best performance-to-weight ratio out of all Power Team pumps.
Remote motor control
The PE552 is also available with a 10-foot remote motor control option for added operator safety. Some models are available with a 25-foot remote control if needed.
Extensive assemble to order options
Like most Power Team pumps, the PE55 can be augmented with various assemble-to-order options, including a variety of valves, valve controls, gauges, reservoirs, and pressure control options.
The PE552 is a good choice for dead ending, but some teams opt for the larger PQ1203 model instead. The PQ1203 is designed for heavy-duty use and for extended cycles. It offers the following features:
Full load operation at reduced voltage
The PQ1203 can start and begin operation at full load, even when voltage levels are reduced by 10 percent.
Internal and external relief valves
The PQ1203 is built with both internal and external relief valves. The internal valve can limit pressures up to 10,000 psi while the external valve can limit pressures ranging from 1,000 to 10,000 psi.
Factory pre-wiring
The PQ1203 is pre-wired at the factory with a three-phase motor that operates at 3 hp and 460VAC. If alternative configurations are required, they can be specified during ordering.
Supplemental equipment that comes standard
Every PQ1203 pump is built standard with thermal overload protection, a heater element, and a motor starter.
Metal housing for electrical components
The PQ1203 is also housed with a durable metal shroud that keeps water and dirt out of the electrical components.
Does Your Crew Need to Repair or Replace a Dead Ender Pump? Our Team Can Help
Dead ender pumps are subjected to near-constant operation and rugged work conditions. While they’re built for maximum reliability, hydraulic pumps need occasional maintenance and, eventually, require replacement.
If your crew requires either, the Flickinger Machine team can help. In addition to supplying the best dead ender and hydraulic pumps on the market, we can help maintain your fleet of pumps for optimal performance. Whether your pump is vibrating, producing noise, or is experiencing efficiency loss, our team can help restore its function and get it back in the field.

Frequently Asked Questions
The dump valve. Most hydraulic pumps can install tensioning anchor sets, but a pump built for dead ending has a dump valve that resets pressure automatically and immediately after each anchor placement. Without one, the valve has to be worked manually between every cycle.
Because of volume. A few extra seconds per cycle sounds trivial until you count the cycles: dead ending crews handle hundreds, often thousands. The PE552 offers advance return for exactly this reason.
It is built on Power Team’s PE55, which is a general-purpose pump. It powers torque wrenches with precise pressure setting for large industrial fasteners, drives hydraulic spreaders where extreme spreading force is needed, and works in foundation repair for lifting and slabjacking, including concrete and steel piering.
The PE552 can take an expanded reservoir up to 10 gallons, comes in a lightweight design, and is available with a 10-foot remote motor control for operator safety, with 25-foot remote available on some models. Like most Power Team pumps it can be configured with different valves, controls, gauges and reservoirs to order.
For heavy-duty use and extended cycles. It starts and operates at full load even with voltage 10 percent low, carries internal and external relief valves, comes pre-wired with a three-phase motor, and ships standard with thermal overload protection, a heater element, a motor starter and a metal shroud that keeps water and dirt out of the electricals.
