Flowserve SIHI Germany GmbH products

Standard chemical process pumps of the Mark3 ISO range arehorizontal, single-stage volute casing pumpswith dimensions to ISO 2858. They meet the technical requirements of ISO 5199, ISO 15783. It is a modular configuration of either bare shaft end or close-coupled design. Shaft sealing options are single or double acting mechanical seals or magnetic drive designs. The benefits are the interchangeability of the back pull-out assemblies and a reduction of spare parts costs.

Horizontal, single-stage volute casingpumps with design features and nominal rating toDIN EN ISO 2858. For pumping of liquids with high temperatures (> 200 ºC) special executions with centre line feet are available upon request. The process design permits dismantling of the complete bearing unit towards the drive end, without the pump casing having to be disconnected from the piping. If a spacer coupling is used it is also unnecessary to disconnect the motor.

Pumps of the series SIHISuperNova ZLN arehorizontal, single-stage volute casing pumps with connections and main dimensions to DIN 24255 / EN 733, plus 19 additional sizes. The design of the pump allows the complete drive unit to be withdrawn from the casing without disturbing the attached pipe work. If a spacer type coupling is used, it is also unnecessary to disconnect the motor.

The SPL is ahorizontal, single stage, end suction pump flanged to a bearing pedestal. The volute casing has integral support feet and is fitted with a replaceable wear ring. Wearing parts can be removed from the drive end without disturbing the volute casing and pipe work. An open impeller is fitted as standard but a closed impeller for pumping liquids containing abrasive solids can be fitted if required.

Pumps of the series SIHISuperNova ZLK aresingle-stage volute casing pumpswith connections and nominal performances according toEN 733 / DIN 24255, plus 6 additional sizes. The design of the pump allows the complete drive unit to be withdraw from the casing without disturbing the attached pipe work. The close coupled design, also, allows dismantling or replacing the motor without disturbing the pump. There is no common shaft for pump and motor, standard motors can be used. The set is a space saving easy to install pump unit.

Pumps of the series ZLI aresingle-stage resp. two-stage pumping units in compact designwith nominal performances according toEN 733 / DIN 24255as well as additional size DN 25, where suction and discharge branch are arranged opposite for direct installation into the pipe work. There is no common shaft for motor and pump. The motors used are of the standard type listed. Thanks to the process design it is possible to withdraw the whole insert unit without removing the casing of the pump from pipe work.

Liquid ring vacuum pumps of the series LOH aresingle-stage displacement pumpsof uncomplicated and robust construction with the following particular features likehandling of nearly all gases and vapours, non-polluting due tonearly isothermal compression,oil-free(no lubrication in the working chamber), small quantities ofentrained liquid can be handled, easy maintenance and reliable, low noise and nearly free from vibration, wide choice of material (therefore applicable nearly everywhere), incorporated central drain and no metallic contact of the rotating parts.

Liquid ring vacuum pumps of the series LPHX/LPH are single-stage displacement pumps and have a simple but robust construction with the following features and benefits like nearly isothermal compression, oil-free (no internal lubrication), capable of handling almost all gases and vapours, able to handle quantities of liquid “carry over”, low maintenance and safe operation, low noise and almost vibration free, available in a wide range of materials, broad range of applications, O-ring sealing as standard, cavitation protection as standard, drain hole as standard, built-in solids drain and rotating metallic parts are non contacting to minimise wear.

Liquid ring vacuum pumps of the series SL are single-stage displacement pumps of uncomplicated and robust construction with the following particular features like handling of all gases and vapours, robust operating behaviour, insensitive to entrained liquids, low noise level, nearly free from vibration, direct drive or belt drive, very little wear because of regular dirt drain (out of the pump) and application of steel as construction material, symmetrical design therefore optionally clockwise or anticlockwise operation by easy shifting of the shaft, no lubricant in the working chamber, compact design, small size, wide effective speed range from 800 to 1,600 rpm, weight-saving construction, leakage proof shaft seal and optionally special seal with radial shaft seal ring and gland packing ring or mechanical seal with bellows.

Liquid ring vacuum pumps of the series LOH are two-stage displacement pumps of uncomplicated and robust construction with the following particular features like handling of nearly all gases and vapours, non-polluting due to nearly isothermal compression, oil-free (no lubrication in the working chamber), small quantities of entrained liquid can be handled, easy maintenance and reliable, low noise and nearly free from vibration, wide choice of material (therefore applicable nearly everywhere), incorporated central drain and no metallic contact of the rotating parts.
