1 Close-coupled pumps Series ES04

3 General Description / Application Pumps of series ES04 are extremely compact units which require very little space. They are particularly suitable for all those applications where space is at a premium, i.e. in crate and bottle washing machines, in air conditioning, refrigeration and heating systems, in surface finishing, dust collection, water treatment, water supply and irrigation plant, also in industrial washing machines. The pumps are designed to handle clean or slightly contaminated media over a temperature range from -20 to +140 C. Even corrosive media can be handled provided pump materials and mechanical seals have been selected accordingly. All pumps are available for 50/60 Hz. Operating range Nominal branch diameter DN Capacity Q up to 550 m 3 /h Head H up to 95 m Operating pressure p up to 10 bar Liquid temperature t -20 C up to +140 C Speed n up to 3600 rpm The maximum casing pressure [bar] permissible for the pumps is determined mainly by the casing material and operating temperature: Operating temperature -20 C up to +110 C +110 C up to +140 C Pump up to up to up to up to Material EN-GJL bar 10 bar 8 bar 6 bar CuSn10-C 8 bar 7 bar 6 bar 4 bar Velocities in pipes and fittings In order to reduce noise levels and friction in suction and discharge pipes caused by excessive flow we recommend the following values: 2 m/s max. in suction piping 3 m/s approx. in discharge piping Designation ES /BS + 2,2/2 Series Delivery branch nominal diameter [mm] Nominal diameter of impeller [mm] Code number for impeller design Several pump s in this range can be equipped with different impellers:.1 = closed impeller, steep curve.2 = closed impeller, flat curve.f = vortex impeller Code letter for type of pump/motor connection BS = Pumping unit with special motor, impeller fitted directly to the extended motor shaft. B = Pumping unit with standard IEC motor, separate pump shaft, connected to motor shaft by means of a rigid disc coupling. Nominal power P2 [kw] Number of poles Example Pumps of series ES04 are non-selfpriming volute casing centrifugal pumps. They are assembled from a minimum number of specifically designed modules. Any necessary maintenance work can be carried out quickly and easily. The main pump components are accessible without the need to disconnect the pipe-work from the pump casing (back pull-out facility). BS units with special motor are assembled in our works and supplied as complete units. B units with standard IEC motor can be put together by the client as the assembly of these sets is extremely simple. The majority of components of the pumps is taken from our range of volute casing centrifugal pumps manufactured to DIN EN standard

4 General The units are manufactured in two basic executions: BS with special motor Electric motor with extended shaft (for mounting of the pump impeller) and special flange (for the connection pump/motor). These units are manufactured with motors up to 7.5 kw at 1450 rpm and up to 11 kw at 2900 rpm. B with standard IEC motor Pump and motor shaft are connected via a rigid disc coupling. These units cover the range of 1.1 to 30 kw motors at 1450 rpm and 1.5 to 37 kw at 2900 rpm. All motors for BS and B units are normally held in stock and can be made available at very short notice. Mounting arrangements Various mounting arrangements are available, irrespective of wether the mounting feet are attached to the pump or wether they are produced without feet. The unit will operate equally reliably in any attitude between horizontal and vertical and latter arrangement, but the motor must always be above the pump. Impeller / shaft In order to attain the optimal efficiency and low NPSH values two different impeller designs are available for many pumps. Code.1 is the impeller with a smaller gap between shrouds, resulting in a steeper H/Q curve. Code.2 impeller has a wider gap and consequently produces a more flat performance curve and, in many cases, also larger capacities. Unless we are instructed otherwise by the client we will select the most suitable impeller for each individual application. A special vortex or two-channel impeller is available for certain pump models. Please contact the manufacturer for details. In case of execution BS (motor with extended shaft) the impeller is stripped on the extended motor shaft. In case of execution B (standard IEC motor) the impeller is mounted on the pump shaft. Pump shaft and motor shaft are connected via disc coupling. Branch positions These depend on the position of the pump/motor feet. If the pump casing has been cast with integral feet the delivery branch is always upwards. The larger units with feet on the motor allow the choice of delivery branch position but the suction branch is invariably axial. Units with motor power up to 1.5 kw (A5, B5) Pump casing with feet, motor without feet: Delivery branch upwards. Alternative positions can be arranged by mounting the complete unit in a different position. Pump casing and motor without feet: Delivery branch position as required, depending on the arrangement of the suction and delivery pipework. The units are extremely simple to install, no need for lengthy site preparation or time-consuming coupling alignment and danger of distorting the coupling. 4

5 General Units with motors 2.2 to 37 kw (B35) Pump casing without feet, motor with feet: Upwards delivery branch but can be turned by 90 to the left or the right. Shaft sealing The mechanical seal fitted to these pumps can be supplied with either silicon carbide/carbon viton or silicon carbide/silicon carbide viton. When pumping hot water exceeding 110 C a mechanical seal with silicon carbide/carbon epoxide-caoutchouc faces will be fitted. Materials The standard materials of construction for the main pump components are shown below together with details of materials available. We reserve the right to change material specification without notice. Special materials (e.g. stainless steel) upon request.

6 Selection chart This chart allows a provisional selection of the pump type most suitable for a given set of operating conditions. In certain cases it may be possible to use the next smaller pump type and this possibility should be included in the final selection. For an exact pump selection our individual characteristic curves as well as our pump selection software WinPump are available. Speed 1450 rpm Speed 2900 rpm 6
