Introduction to Concentric D Series Hydraulic Pumps Concentric o ers one of the widest selections of gear pumps and hydraulicmotors in the industry. All Concentric products are designed to provide solutions to our customers’ application challenges. Concentric D Series Hydraulic Pumps are compact, external gear models for use in pumping uids with lubricating qualities. Suitable for use in a wide variety of applications, including agricultural, construction, transmission charge and lube, and diesel fuel transfer. Our D pumps are designed to provide reliable, long life service under rugged conditions. D Series pumps are built with cast iron bodies and hardened steel gears. The Concentric line of D Series pumps covers a displacement range from 0.23 in.3 (3.8 cc) to 1.395 in.3 (22.9 cc). Single, tandem, triple and quadruple con gurations are available. The D Series also o ers a large selection of shaft and ange options tomeet your application requirements. Installation Information FLUIDS- Most premium grade petroleum base uids can be used with the D Series pump. Optimum operating viscosity is 16-63 cSt (80-288 SSU) at maximum rated speed. Minimum operating viscosity is 10 cSt (59 SSU). Maximum operating viscosity is 750 cSt (3409 SSU). Maximum cold start viscosity is 2000 cSt (9091 SSU). Contact Concentric for additional information regarding the D pump performance using other uids. OPERATING TEMPERATURES - Fluid temperature range (Mineral Oil): Max. 93oC (200oF) continuous and Max. 105oC (221oF) intermittent. FILTRATION- Proper ltration is critical to the trouble free operating of any hydraulic system. For optimum pump life at maximum pressure ISO 4406/1986 (Code 18/14) is recommended. A 10-micron lter sized to accommodate full system return ow is recommended for most operating environments.

Getting the most out of your machinery often depends on close integration between all components. An organisation that manufactures and integrates all the diverse components of a drivetrain provides the experience to help you select the best component combination for your application. jbj Techniques’ in-house design team and manufacturing facility provide tailored solutions for your applications at competitive prices with quick delivery. The following examples are a simplistic view of how jbj Techniques assists customers. Hydraulic Adaptors Designed primarily to allow the close coupling of hydraulic pumps to a variety of prime movers, such as diesel / petrol engines, electric, air or hydraulic motors, they can also be used in the connection from prime mover to alternative driven parts i.e. gear boxes, generators, water or vacuum pumps etc. An additional range of engine front PTO adaptors, which provide additional connection between the engine pulley and the driven part are also available. The kit comprises of a and flexible bellhousing drive that are fully machined to suit the coupling driving and driven components. These can be to suit either shaft to shaft, flange (flywheel) to shaft or even flange to flange connections. Getting the most out of your equipment will demand close integration between all components. In specifying jbj Techniques as your preferred supplier, you will have selected a company with the experience to specify, manufacture and integrate all of the diverse components that will ensure the best component combination for your application. jbj's in house design team and manufacturing facility provide tailored solutions for your applications at competitive pricing and on-time deliveries. Pump shaft alignment is key to preventing unnecessary wear and damage to the pump shaft seal and bearing. Improper alignment may lead to premature pump failure. Also to be considered are unwanted torsional resonant frequencies in the system which can quickly cause damage to components in the drivetrain and reduce system life and performance. Improper pump installation can lead to premature failure, increased maintenance costs and reduced production levels of final product. jbj Techniques can advise on the correct installation of into Industrial / hydraulic pumps mobile / marine / machine tool / agricultural / offshore industries and can specify complete driveline systems from their extensive range of components which are available from stock or manufactured to order, albeit simple or complex, standard or bespoke. Electric Motor – Hydraulic Pump Adaptors (safe area) jbj Techniques Limited offer the most comprehensive range of in Europe. bellhousings Designed to connect electric motors with frame size IEC D56 - D400 (0.06kW – 750kW) and can be compatible with electric motor 'B5' or 'B14' flange configurations. Accompanying the metric frame units above is a complete range of mountings to suit Nema and imperial frame motors with 'C' face or 'D' flange fitments. With fully machined , torsionally flexible couplings or available, jbj ensure torsionally rigid couplings the most suitable combination is selected for the application in hand. As an example spider couplings are available in various materials including aluminium, grey cast iron, nodular iron, steel and stainless steels and can be finish machined with parallel, taper or splined bores to DIN, SAE, ANSI or ISO standards. Bellhousings can be manufactured in aluminium or cast iron material as standard, however, units can be produced in a variety of exotic materials on request. The aluminium product range is produced in either monoblock or composite formats giving great flexibility in design and allows for early delivery time, often with same or next day delivery possibilities. For applications where low noise levels are a quality products for mechanical & fluid power #DriveLineHarmony www.jbj.co.uk an excellence in engineering
ensuring a continuing high quality service in which customers can have complete confidence. “ “ requirement then a complete range of antivibration and noise reduction components add to the range. Electric motor – Hydraulic Pump Adaptors (hazardous area) Designed to meet the exacting safety standards of the offshore and chemical process industries, jbj Techniques produce certificated to adaptor kits Directive 2014/34/EU II2GD-IM2-TX -50 C< Service Temp < +105 C. Harmonised standards BS EN 1127:1, BS EN 13463:1, BS EN13463:5, BS EN 50303, BS EN 1834-1,BS EN 1834-3. Generally manufactured in Cast or Nodular iron, bellhousings can be produced in steel, stainless steel or alternative exotic materials on customer request. Couplings supplied for these applications are the jbj Techniques 'JXL' pin and bush range which provide an anti-static and flameproof drive which meet zone 1 area requirements, conforming to all of the above standards. Also available are spider and gear couplings which are certified to zone 2 standards. (Contact jbj Techniques for details). An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level. With a vast array of components to select from, jbj are well placed to provide all required components to support the required cooling system. Diesel Engine – Hydraulic Pump Adaptors A complete range of bellhousing and couplings exist for the connection of a diesel engine flywheel to a specified driven component, be it an oil hydraulic pump, water pump, generator or similar device. With the bellhousing available in various materials to suit all application areas. With a standard range to connect Diesel engines with SAE dimensions from SAE '6' to SAE '0' jbj are well placed to satisfy the majority of customer requirements. Couplings to complete the assembly are available in either torsionally flexible or torsionally rigid design ad can be supplied to suit SAE flywheel dimensions from SAE 6.5” to SAE 18”. For hydraulic pumps to be mounted to engines that do not conform to SAE dimensions, we offer a full range of assembly parts, some of which (but not all) are shown here » for diesel engines All bellhousings within this range can be finished machined to accept any, piston, vane or gear pump interfaces requested by customer.
