The MAH 2X1.5B is a heavy‑duty horizontal centrifugal slurry pump designed for abrasive slurries. The designation 2X1.5B typically refers to a 2" suction and 1.5" discharge size in the MAH product line used in sand mining and similar industries.
Typical applications include sand and gravel pumping, dredging, tailings transport, mine dewatering, mineral processing, coal preparation, and other abrasive slurry transfer duties.
It is a single‑stage, cantilevered horizontal pump with replaceable wear parts (liner, impeller, throatbush), robust shaft and bearings, and options for metal or rubber wet ends to resist abrasion and corrosion.
Common wet‑end materials are high‑chrome white iron (HCWI) for excellent abrasion resistance and natural or synthetic rubber linings for handling finer, more abrasive slurries. Other alloy options may be available on request.
Sealing options typically include gland packing, expeller (self‑acting) seals, and single or double mechanical seals with appropriate seal flush arrangements depending on application requirements.
Select based on required flow and head, slurry density and viscosity, maximum particle size, and abrasiveness. Provide these parameters to the manufacturer or distributor so they can match a pump curve, materials and impeller trim to your application.
Maximum particle size and allowable solids concentration depend on impeller geometry, clearances and wet‑end materials. For small 2x1.5 class pumps typical max particle sizes are in the low millimeter range; confirm exact limits with the manufacturer using your slurry specification.
No. This type of horizontal centrifugal slurry pump is not self‑priming. It normally requires a flooded suction or an external priming device to ensure proper operation.
Install on a rigid foundation, align pump and driver accurately, keep suction pipe short with minimal fittings and no air leaks, provide proper inlet submergence, and include an isolation valve, non‑return valve on the discharge, and gauges for monitoring.
Regularly inspect wear parts (impeller, liners, throatbush), monitor vibration and bearing temperatures, check seals and gland packing, keep lubrication at recommended intervals, and maintain a spare parts inventory for quick replacement.
Keep common wear parts: impellers, front and rear liners, throatbushes, shaft sleeves, bearings, mechanical seals or packings, and fasteners. The exact list depends on your duty cycle and lead time for parts.
Cavitation: check NPSH available, reduce suction lift, increase inlet submergence. Excessive wear: verify material selection, correct pump selection (impeller and speed), control solids size and concentration, and maintain proper clearances. For persistent issues consult factory support.
Operating temperature and pH capability depend on selected materials. Rubber‑lined pumps are typically limited to moderate temperatures (often up to ~80–90°C) while metal‑lined pumps can handle higher temperatures. Chemical compatibility depends on liner/impeller material — consult the manufacturer with your slurry chemistry.
Contact the pump manufacturer or authorized distributor with the model number (MAH 2X1.5B) and your application details. They can provide pump performance curves, dimensional drawings, material options and installation manuals.
Provide the full model (MAH 2X1.5B), required duty point (flow and head), slurry properties (density, max particle size, concentration, pH, temperature), desired materials, seal type, motor power and voltage, rotation direction, and any preferred accessories.
