How do I choose the right hydraulic pump?
30.06.2024 | In this video Parker Hannifin Numerous tips on what you should consider when choosing a hydraulic pump.
Bent axis pumps and motors with constant displacement
01.10.2023 | Parker Hannifin presents the F10 product series (pictured above), consisting of bent axis pumps and motors with a fixed displacement, especially for medium duty. This series builds on the F11 and F12 models, which are manufactured by the Pump and Motor Division Europe. The F10 series offers energy savings, reliability and durability. It is ideal for applications in agriculture, construction, mining, shipping, offshore, oil and gas and transportation.
With displacement of 30 cm³ to 125 cm³ and designed for open and closed circuit transmissions, the F10 series offers exceptional efficiency and significantly reduces power losses thanks to the patented spherical piston concept. The new series adopts the proven design of the high-performance F11 and F12 series, including double-tapered bearings and ring gear synchronization.

The F10 series scores with up to 13% smaller housing and a 25% lower weight compared to the F12. This makes installation easy. The high volumetric efficiency of up to 96% underlines the efficiency of this new product line.
Christian Bengtsson, Product Manager at Parker Pump and Motor Division Europe, emphasizes: "The new F10 product series is probably the most efficient medium-duty pump and motor on the market. When developing the F10 series, we focused on sustainability and low total cost of ownership, as well as long service life and high reliability. We can significantly reduce operating costs by significantly reducing power consumption and supporting OEMs' goals to reduce emissions and comply with future environmental regulations."
Available in ISO, SAE and cartridge versions, the F10 Series offers flexible shaft options as well as a wide range of speed sensors and integrated valve options.
High pressure pumps up to 350 bar with flow rates 1,6 to 5 cm3/U
07.03.2019 | The radial and axial gap compensation of the internal gear pumps from Eckerle Technologies leads to very good efficiencies across the entire speed range over the entire service life, even at high temperatures and low oil viscosities. The manufacturer has now expanded its portfolio downwards with the EIPS1 series in delivery sizes from 1,6 to 5 cm3/rev.
The low flow pulsation and the associated low noise are further advantages of this robust pump system. The flow sizes from 5 to 250 cm3/rev have long been covered by the series 2 to 6. The pumps can be used up to 350 bar and their compact design offers excellent opportunities for customer-specific solutions such as valve integration, multiple pumps or adaptation to the installation situation.
The pumps are suitable for use with variable speed drives and already offer the option of energy recovery in battery-powered vehicles as standard. Special solutions are also offered as four-quadrant machines for the closed circuit.
Pump 4.0 - benefits and added value in the focus of the operator
21.04.2018 | Which trends dominate in the process industry? In addition to the long-running issue of energy and raw material efficiency, these are primarily 'modular plant construction' and, of course, 'digitalization'. These innovations are also changing the world of industrial pumps. Grundfos Pump 4.0 is therefore ready.
High pressure plunger pump with flow rates up to 4000 l / min
13.11.2017 | The “Quintuplex” plunger pump from Interest generates large volume flows of up to 4000 l/min and high pressures of up to 3500 bar. The requirement for the development of the K 120000-5G came primarily from mining and steelworks. Today, for example, ten to fifteen identical pumps are sometimes used in the descaling of rolled steel products.
The new model is 50% more powerful as the most powerful pump to date with 800 kW motor power. A crucial design difference between the new 1200 kW pump and the manufacturer's previously known plunger pumps is the drive concept. Instead of the integrated gearbox with double helical gearing from our own production, an industrial gearbox with a separate housing is used.
This reduces production costs and allows the reduction to be easily adapted to individual requirements – even retrospectively. Other differences to 800 kW pump are the number of crankshaft bearings (six instead of four) and the pressure oil lubrication of the large-dimensioned crossheads.
The K 120000-5G is manufactured with two different head types. In the Ultra high pressureFor example, the 158 l/min version provides a maximum of 3500 l/min at a pressure of 407 bar or 1530 l/min at 3939 bar. If the user's focus is on maximum delivery capacity, the pump (with a different head type) achieves a maximum of 115 l/min at 900 (with 155 kW) or 1200 bar (with XNUMX kW). The plunger pump is compact and works energy efficiently.
Canned motor pump for chemical and process engineering
08.06.2015 | Presented for the first time KSB the absolutely leak-free canned motor pumps of the “Ecochem Non-Seal” series. These are designed for the transport of dangerous, aggressive, flammable and explosive liquids. They are also used for the pumping of toxic, very hot or cold as well as volatile and valuable liquids.
The series is a combination of the Chemical standard pump "Mega CPK" and the canned motors from Nikkiso. The pumps have dimensions in accordance with the ISO 2858 standard and they meet the requirements of the DIN/EN/ISO 15783 and API 685 standards. The energy-optimized electric motor design ensures economical operation. The low-noise motor has a corrosion-resistant can made of Hastelloy (2.4610). The series is available in four standard variants: one version each for standard chemistry, for heat transfer media, for polymerizing or ferrite-containing media, and in a special variant for low-boiling substances and liquid gases.
The units are for Ex protection II 2 G c Ex de IIC according to ATEX, TR and IEC Ex, temperature classes T1 to T5 and designed for standard conveying medium temperatures from -40° to +400 °C. The maximum discharge head is 236 m and the highest discharge flow is 690 m3/H. Sliding bearings made of pure silicon carbide or a silicon carbide-graphite compound lubricated by the medium offer the possibility of optimally adapting the bearings to the operation of the pumps and to the medium.
In order to prevent blocking by media which become viscous or solid during cooling down, the pump housing can be optionally heated. The engines have a power up to 75 kW. 16 different motor sizes and a modular system for engine mounts are available.
