Eccentric Screw Pumps SERIES ANP

Use Suitable for pumping low- to high-viscosity liquids, neutral or ag-gressive liquids, undiluted or abrasive liquids, liquids containing gases, liquids prone to foaming, including liquids with fibrous or solid particles.

Main fields of application Wastewater and clarification plants, chemical and petrochemical industries, paper and cellulose, soap and grease, paint and coat-ings, food and beverage, plastics, ceramics, agriculture, sugar in-dustry, shipbuilding, etc.

Function Self-priming, rotating displacement pump. The pumping elements are the rotor and the fixed stator. These two parts contact each other at two points in their cross-section. Viewed along the length of the pumping elements, these points form two sealing lines. As the rotor turns, sealed chambers are created. The content of the chambers is moved continuously in the axial direction from the suction side to the pressure side of the pump. Despite rotation of the rotor, no turbulence results. The consistent chamber volumes eliminate crushing forces and ensure an extremely gentle, low-pulse pumping action.

Structural design Discharge casing, stator, suction casing, and lantern base are held together by means of external casing connection screws (clamp bolts). The suction casings of all sizes are provided with large suction cross-sections. The stator is vulcanized into a pipe and is equipped on both ends with external collars that provide reliable sealing with the suction and discharge casings and protect the sta-tor casing from corrosion.

The exchangeable stuffing box casing or mechanical seal (can be retrofitted to another seal type) is located between the lantern base and suction casing.

The drive shaft is carried in bearings in the bearing housing. The drive torque is transmitted to the rotor via the drive shaft and a coupling rod. Both ends of the universal joint shaft end in liquid-sealed encapsulated pin joints that are designed to be very simple and robust and absorb the rotor’s eccentric movement without dis-turbances.

Shaft seal Shafts are sealed by cooled or uncooled stuffing boxes or cooled or uncooled, non-balanced single or double-acting mechanical seals which require no maintenance.

The type of seal and the material pairings are adapted to suit the particular operating conditions which exist in any given case.

For further details see page 5.

In any given size of pump, the housings for the various types of stuffing box or mechanical seal are interchangeable with one an-other. The various parts of the housings for mechanical seals form a modular system and can be combined with one another without any difficulty should the pump be converted to a different type of mechanical seal.

Mechanical seals to DIN EN 12756 can be fitted (double mechani-cal seal excluded).

For further details see pages 4, 5, 6, and 7.

Bearing The drive shaft is carried in particularly rugged deep groove ball bearings which are designed to withstand all appearing radial and axial loads. The bearings are lubricated for life.

For further details see page 4 and 6.

Exchangeability of parts The components of all progressing cavity pumps are designed to be modular. As a result, a customer who employs several pumps from various series and designs will be able to maintain a simple and cost-effective stock of reserve parts.

Drive For possible types of drive see page 9.

Drivers produced by any manufacturer can be used. Technical characteristics and dimensions should be taken from the docu-mentation issued by the manufacturer.

Installation Depending on the shaft seal, ANP pumps can be installed horizon-tally or vertically. When installed vertically, a “motor down” ar-rangement should be consulted the manufacturer.

The pump and driver are connected together via a flexible cou-pling or an intermediate transmission (generally a belt drive) and are mounted on a common baseplate. Dimensions of assemblies available on request.
