4 GENERAL DATA Technical data: Capacity: ead: Temperature: ump type key Example: impeller diameter in cm design code rotation face discharge DN in mm stages Design: up to l/s up to 3 m up to 1 C 3 MSD -3 The MS are process duty multistage centrifugal pumps in ring section design, designed(produced) for moderate to high pressure heads available in five basic sizes. The MS pumps are offered with suction and discharge flange according DIN standard, depending on the pressures and number of stages involved. The suction and pressure bodies can be turned for 9 in both directions, which enables the pumps to be mounted and adapted to the requirements of the installation. Axial thrust is relived by means of a drum mounted on the shaft inside the discharge hull, rest of the thrust bears one of the roller bearings. The impellers are centrifugal of closed type identically fixed to a shaft, supported on two roller bearings. The shaft sealing in standard execution is executed by means of soft cord packing and the shaft is protected by hardened sleeves. As option mechanical cal seals are available. ydraulic performance extends to 1 l/s capacity and 3 meters head, which compare them to all favorite pump types and makes them ideally suited for the most demanding industrial and process services. The MS pumps in standard executions with soft seal packing can be used for handling water up to temperature of C, then as water supply pumps, irrigation and drainage pumps in agriculture, water circulation pumps, in mining... In the version with mechanical seal they can, (besides the used listed above), be applied in oil industry for the transport of thin oils, petroleum products up to the temperature of C. In special version these pumps can be used in chemical and process industry. owever, in each particular case of pump selection, especially, if they are intended for special purposes, it is necessary to consult the manufacturer. Standard material executions: - ump case, shaft bearing bracket and impeller in cast iron. - ump shaft and shaft sleeves in stainless steel. - Other material combinations are available on special demand or due to the properties of the liquid. Applications: ydraulic performance extends to 1 l/s capacity and 3 meters head, which compare them to all favorite pump types and makes them ideally suited for the most demanding industrial and process services.

5 Flexible coupling: -Standard version -Spacer coupling Bearing assembly with shaft: The bearings are located in two bearing housings, which are positioned at both sides of the pump lubricated with nipple greasers. Depending on pump size deep groove ball bearings or double-row roller bearing is used at drive end, and a pair of matched angular contact ball bearing or cylindrical roller at the non-drive end. The protection ring on the shaft prevents liquid from entering the bearing housing. Shaft sealing: The shaft sealing could be arranged by soft packing or mechanical seal. In soft packing arrangements the shaft is protected by replaceable stainless sleeve while the stuffing box is furnished with lantern ring for introduction of cooling liquid into the packing. On special demand the pumps could be furnished with mechanical seal in accordance with the characteristics of the liquid and the operating conditions. Wear Rings MS pumps have replaceable wear rings, providing consistent pump efficiency. The inner diameter of the MS pumps wear rings matches the impeller inlet diameter, which produces undisturbed flow conditions. Cylindrical clearance between impeller and wear ring is of a special design which reliability and effectiveness have been well proven. It has two or three close-contact surfaces between impeller and ring. Leakage is therefore limited, which ensures high efficiency and no fibres trapped in the clearance. Range of program: A wide variety of models makes it possible to select a pump to suit any fields of the industry and the agriculture. roper choice is important in order to minimize the energy consumption and to assure long trouble-free operation of the pump. erformance The performance curves are given in the diagrams bellow, indicating: Q-, Q-, Q-efficiency, Q-NS. MS pumps can operate continuously in whole the operating region within the motor power limitation. All the pumps can run at different speeds, depending on the size of the pump and the customer requirements. For higher speeds it is necessary to check the pump limitation. The performance curves are based on a liquid density of 1 kg/m³. For working fluid density below or above 1 kg/m³ it is necessary to multiply the power. Drive The drive is generally a direct coupled electric motor, using a flexible coupling. For sizing of the drivers you have to add a minimum of 1 to 15% to the pump absorbed power, depending on operating condition, eventually a higher could necessary. 4/5

12 GENERAL DATA Stuffing boxes Single mechanical seal shaft Gland packing with or without lanternring. roduct recirculation or external sealing liquid can be used. Standard mechanical seal for clean or slightly contaminated liquids at medium inlet pressures. Bearing Bracket Depending on pump size, a deep groove double row ball bearings is used at the drive end, or a cylindrical roller bearing and a pair of matched angular contact ball bearings at the non-drive end. The intermediate bearings are used at vertical designed pumps. The bearings are protected against moisture and dirt ingress.

13 GENERAL DATA - Sectional drawing of MSS Stuffing boxes One way to balance the axial thrust in a multistage pumps is to arrange the impellers in opposed direction. With an even number of impellers, such an arrangement can eliminate the axial thrust completely. Another way to balance the axial thrust is to use a balancing drum. In such case, the axial thrust is being taken up by a single drum. This device is subjected to total pressure developed by the pump on one of its faces. On its other face, it is subjected to the suction pressure at the inlet of the first impeller. 1/13
