This is particularly evident in the high level of creative innovation in recent years, with many new products in the field of high-efficiency pumps. alm places great demand on the quality of its products Modern production facilities and processes are just as much part of the corporate concept as well thought-out quality management. Internal testing facilities and ISO-certified quality management are indispensible factors of success. Long-standing customers value the high demands placed on the quality of the products and the flexibility with which alm meets custom requirements. alm is helping to shape the future as a reliable partner A company is only as good as each of its constituent parts. This is why motivated and experienced employees are a key element of success at alm. Flexibility and expertise head the list of priorities for being a reliable partner to our customers. Together with over employees, alm s objective is to make a lasting contribution to the future with its products. alm high efficiency pumps already fulfil the tightened requirements of the eco-design directive from until. The new EP Optimo features an LED display showing the modes of operation, the pressure head, the total electrical input power as well as error codes. As standard, it is delivered with a plug and with installation length mm also the insulation shell is included in delivery. No insulation shell is offered for mm installation length. For the EP Optimo Basic version, we ommit features such as display, insulation shell and plug but we fit a premounted cable in order to be able to offer a very well-priced model for different applications for which these features are neither required nor necessary. New in the delivery range are condensate pumps for gas and oil condensing boilers called Lift and a complete line of large EP Optimo L+ circulators. With this new high quality line of threaded and flanged circulators the whole replacement and new buildings demand for heating, air conditioning and refrigeration applications can be covered from / m to DN/ m. The new EP Optimo L+ complements the existing low cost series EP Optimo L which have been designed for the main types of applications with head or m.

General information alm type key EP Optimo -. G Pump types Nominal width pipe connection Pressure head in meters water column Speed switchable or electronically controlled Installation length (mm) Installation options Circulation pumps must be installed with a horizontal shaft. Construction alm circulation pumps are inline wet rotor circulators. They are maintenance-free and fitted with opposite-facing connecting nozzles of the same nominal width. The pump, motor and terminal box comprise one unit and are optimally matched with one another. A stainless steel can separates the rotor chamber and stator winding. It features static seals at both ends. Bearing Both bearings are made of oxide ceramic. This is particularly suitable because of its hardness, surface quality and corrosion resistance. They ensure smooth running and a long service life. Air cavities in the can well are evacuated via the hollow shaft. EEI The benchmark of the most efficient circulators is EEI.. All alm m high efficiency pumps fulfill the requirements for BEST in class.

Using proportional pressure mode PP ( ) is the best setting for such heating systems, as here the pump decreases head at lower flow. If the main supply heating pipe has not to be taken into consideration, because it is short or has its own pump (likely for underfloor heating systems with in mixing units integrated pumps or drinking water systems), best mode to go with is constant pressure mode CP ( ). In such heating systems, it is important always to have constant pressure for the radiators or ufh-circuits, as the pressure loss in the main pipe is not considered and all other consumers are installed in parallel, which does not influence the maximum pressure loss.

EP BB Babelbox BB and EP PWM, S product group Supply voltage: V Power input:. W Signal input leading edge: - V Signal input trailing edge: - V Signal input wave packet: - V, z Signal input power consumption:. ma PWM output: V DC, ma Frequency: z Ambient temperature: C to + C Cable connection input: x M Dimensions: x x mm Weight:. kg Use The Babelbox BB is designed for use in heating systems in which an on-site controller pulses a standard pump via the power line and this pump is to be replaced by a high-efficiency pump. igh-efficiency pumps do not react to a pulsed power line and therefore cannot simply substitute for a standard pump. Interposing the Babelbox BB solves this issue while retaining the control functions of the system. Mode of operation The BB automatically detects if an on-site controller is pulsing the power line via a wave packet or is outputting leading or trailing edge voltage. The BB converts this into a PWM signal which is identified by the alm PWM pump. Just like the standard pump previously, its power is also then controlled. An integrated LED shows the presence of voltage from the on-site controller. Main areas of use All applications in which a standard pump controlled externally by the power line is to be replaced by a high-efficiency pump. Return flow boost Solar installation Differential temperature controlled underfloor heating Storage charging circuit Freshwater station (suitability should be checked with the manufacturer due to the highly sensitive controlled system) Installation Stable cable bushings and elevator terminals enable easy installation. The BB must be connected to V voltage, with the PWM pump and the pulsed power line. Fully automatic detection of the input signal means no further settings need be adjusted. Motor (high efficient ECM technology) Power supply nominal: - V, - z Power consumption: Version m (- W); Version m (- W) Power consumption stand-by PWM:.

It was previously not possible to replace standard heating pumps driven by wave packet, leading or trailing edge control with high-efficiency pumps. For the first time, this can now be done with the Babelbox BB. Fully automatic signal detection! Typical high-efficiency pumps require a V constant voltage supply. If, however, a high-efficiency pump is connected to a variable power voltage supply (solar controller, freshwater station controller, charging controller etc.), it reacts neither to a wave packet nor leading edge control as desired. This is where the Babelbox BB from alm comes in. It independently and fully automatically detects which signal is being output by the controller of the standard pump and converts it into a PWM signal which can be understood by the high-efficiency pump, controlling the latter in just the same way as the previously installed standard pump. The voltage supply for the high-efficiency pump itself comes from a separate V connection.
