Today concrete pumps are predominantly operated by hydraulic systems. Putzmeister places its trust in the benefits of free-flow hydraulics because the most important performance factors are the concrete pressure, low-loss oil delivery and costs.

When large quantities of concrete are pumped, large quantities of oil also flow inside the hydraulic system. More power is transferred inside a closed free-flow hydraulic circuit because the oil is conveyed from the pump to the drive cylinders without loss. The adapted hydraulic System ensures extremely powerful interaction between components. Compared to the open circuit, this ingenious drive technology requires significantly less oil and does not generate as much heat. The system is also economical to operate because it achieves a high degree of energy efficiency and is easy to service.

The KOS pump is particularly suitable for conveying highly viscous sludges and other material with a high proportion of extraneous material. The main fields of application of the KOS are with materials which present the most extreme requirements, such as dewatered sludges containing solids, oil sludges, high viscosity solids and so on. For extreme applications, a wide range of task specific components and functions are available from Putzmeister. The pump’s simple design and the fewer wear parts offer a robust, low maintenance pump with low operating costs.

The seat valve pump is used for arduous applications. The HSP series is used with paste-like and highly viscous material with a low content of foreign bodies and small particle sizes (< 5 mm).

Precise sealing of the valves means that extremely high pumping pressures can be achieved. The principle behind the design of the hydraulic and pumping pistons is the same as in the Putzmeister KOS and KOV series. This ensures maximum reliability and availability.

Two special features of the Putzmeister design are that not only is it a simple matter to replace the valves but the design also means a long service life for all wearing parts. Valves and valve seatings are made of highly wear-resistant steels and can be used at either end. This doubles their service life. Valves can be easily replaced without dismantling the delivery lines.

A pulsation-free conveyance can be achieved with the PCF system (Pressure Constant Flow,optional). All of the familiar Putzmeister options and variations (ex-protection, materials) are availablewith the HSP series on request as well.

The valves are passively operated, which makes it an inexpensive pump with maximum availability. There are no issues or complications when pumping fine-grained mortar and low consistency slurries, even when they contain foreign bodies up to 10 mm in size.

The heart of everypiston pump. These power packs have proved their effectiveness more than 10,000 times with concrete pumps and now they power up industrial pumps that convey the material.

Depending on the quantity of oil needed, an open or closed oil-circuit can be used. The closed oil-circuit is used when reaching large delivery capacities, which means considerable cost-savings. The oil-circuits are designed for hydraulic pressures of up to 300 bar. This equals delivery capacities of up to 150 bar, for a short time up to 160 bar.

Depending on your application, the sliding frame can take the form of a rectangular silo discharge system (ladder system) / PDSL or a round silo discharge system / PDSF. The ladder system with multiple parallel sliding frames is particularly suitable for wide or long receiving bunkers. This ensures an efficient transmission of force and increases the availability of the system thanks to the redundancy. The product range includes silos and bunkers from 10m³ to 1,000 m³ for loading trucks and for feeding sludges to solid pumps and their onward conveyance. Material is discharged from the silos by means of specially adapted screw conveyors, with a lateral or central discharge. If several end users have to be supplied, multiple discharge augers can be used.

As an alternative to steel silos, the receiving bunkers and sometimes the storage silo can be made of concrete. Putzmeister designs and delivers in these cases the sliding frame technology and discharge screws as well as the special concrete embedment parts.

The Putzmeister sliding frame system has been designed especially to meet the requirements of 24/7 operation. Thanks to modern Finite Element Analysis and proven Putzmeister hydraulic components, the sliding frame’s design, as well as its service life is optimised .

One important feature is the space-saving design achieved by integrating the sliding frame piston rodinto the silo base tunnel. The piston seal used in the high pressure pumps reliably prevents thesludge from escaping.

Putzmeister concrete pumps with the S-Valve are continually setting new world records in vertical and horizontal delivery. For example, in 1994 at Riva del Garda in Italy concrete was pumped vertically over 1,745-feet (532m), or a pump height of 1,990-feet (606m) at the Burj Khalifa job site. Even in these cases both machines and accessories were not operating at their limits, Putzmeister pumps can be counted on to perform reliably on demanding projects around the world.

With high delivery pressures up to 1,855 psi (130 bar), and maximum delivery outputs of up to 238 yd³/h (182m³/h), Putzmeister pumps are ideally suited for all concreting tasks.

Ideal for high pressure applications, our Big Mouth S-Valve effortlessly handles extremely harsh concrete mixes. It"s huge 9-inch (230mm) intake opening provides a superior filling rate, while the long and controlled reduction of the S-Valve ideally forms the concrete for pumping.

Stationary concrete pumps with the S-transfer tube are continually setting new world records in vertical and horizontal delivery. For example, in 1994 at Riva del Garda (.pdf, 372 kB) in Italy, concrete was pumped vertically over 532m! Or a pump height of 606m at the Burj Khalifa job site. Even in these cases, both the machines and accessories were not operating at their limits. Even when dealing with difficult concrete Putzmeister machines can be counted on to perform continiously and reliably.

Wherever extremely stiff and highly abrasive mixes are encountered this system is used. Of course it is also available with truck-mounted concrete pumps. In pre-cast factories you will find always find a piston pump when it comes to high strength concrete, steel fibre concrete or when there is a longer distance to cover.

The S-valve is the first choice for concrete pressures above 85 bars. This is especially useful for long pumping distances over stationary pipelines. The Putzmeister S-valve is especially designed for long life and high concrete pressure. This results in long service intervals and increased availability of the machine. To extend the life of the S-valve, the inside wall can be rebuilt by hard face welding.

Slick Willie 2 concrete pump primer is a product designed to avoid concrete hoses to plug during the first strokes pump job. This non-Alkaline product is applied into your pumping system before every job, lubricating the walls of your hoses or pipes, which allows the concrete to flow smoothly.

Concrete pump primer is one of the cheapest insurances and this is why. When concrete is first pumped into the hoses, it will loose water in the process. This water would be absorbed by the dried hoses, causing concrete to loose its pump ability, so YES, you DO need to prime your system.

Say you start pumping 200 feet with a 6″ slump, at the end of 200 feet, you might end up with a 4″ to 3″ slump depending on the heat and conditions of the concrete, giving you as a result a higher chance of plugging your lines up. So It’s important to lubricate the walls of your system, you can do this with a concrete pump primer, Portland cement or just water.

Concrete pump primer: this product is designed to solve the problems above. First is environmentally friendly, biodegradable, easy to use in small convenient 4 oz. bags, it becomes like a jelly that coats completely the walls of your hoses or pipes.

Slick willie 2 is Americas favorite concrete pump primer, this industry leader combines speed and performance like no other primer before, the primer formula is packaged in compact 4oz. bags, making storage and transportation simple. Slick Willie 2 is safe for the environment and great for your pump and hoses.

Concrete pump primers are extremely important for your concrete pump. It ensures that the concrete being pumped, can make it easily through the hoses when you first start pumping.  This biodegradable material will ensure the longevity of your hoses and the ease of use on your concrete pump. What happens is once you start pumping, your hoses will start taking water away from the mix reducing the pump ability of the material therefore causing you to plug and delay your job.

Concrete pump primer basically creates a gellous material that will coat the walls of the hoses as concrete travels through it. Basically, you apply the concrete pump primer first and you start pumping it into your hoses, and then you pour the concrete into the hopper and pump it down, having the concrete pump primer in front of the concrete material. And since it is biodegradable, you can pretty much allow it to be disposed of anywhere in the job site.
