P-BA and PC pumps

The P-BA and PC series pumps are submersible pumps designed for pumping mine water and other liquids containing chemical and mechanical impurities.

P-BA and PC pumps are used in mining as face pumps for drainage of mining workings. The design of the P-BA and PC pumps in the explosion-proof version (Ex d I Mb) enables their operation in mining plants in areas at risk of methane and/or coal dust explosion, as a device of group I category M2.

Outside mining, P-BA and PC pumps are used for drainage of excavations and wells, especially where contaminated liquids are pumped and there is a risk of explosion.

Typical Applications & Deployment
– Drainage of mining workings (Face pumps)
– Methane & coal dust hazard underground areas
– Pumping mine water with chemical & mechanical impurities
– Drainage of excavations & deep construction pits
– Well drainage with explosion risk potential
Building

Building Parameters

Submersible, single-stage centrifugal pumps, with closed impellers mounted directly on the electric motor shaft. On the inlet side, the impeller is closed with a suction cover with a brass insert. The base is a suction strainer made of perforated sheet metal. The motor shaft is sealed by a double mechanical seal.

Submersible Single-Stage Centrifugal Design

Submersible, single-stage centrifugal pumps, with closed impellers mounted directly on the electric motor shaft.

Suction Cover with Brass Insert & Perforated Strainer Base

On the inlet side, the impeller is closed with a suction cover with a brass insert. The base is a suction strainer made of perforated sheet metal.

Double Mechanical Shaft Seal

The motor shaft is sealed by a heavy-duty double mechanical seal ensuring maximum isolation and long component service life under slurry load.

IP68 Electric Motor Cooled by Pumped Liquid

The drive comes from an electric motor above the pump, cooled by the pumped liquid, with protection class IP68 and designed to work immersed under the surface of the liquid.

Quick-Connect or Multi-Cone Discharge Connector

The discharge connector is made as a quick-connect or multi-cone tip, enabling rapid connection of a flexible hose for agile mobile deployment.

Comprehensive Thermal & Ground Continuity Protection

The pump unit is equipped with thermal protection of the pump and motor (bimetallic limiters) and a diode unit for monitoring ground continuity.

Explosion-Proof Mine Certification (Ex d I Mb)

Certified for operation in underground mining areas exposed to methane and flammable coal dust as a Group I Category M2 device, equipped with bimetallic thermal limiters and ground continuity monitoring.

Product Features

Key Engineering Features

Two Material Versions (Basic & Salt-Resistant)

P-BA pumps are manufactured in two dedicated material versions: basic for standard drainage duty and salt-resistant for aggressive saline mine waters.

Explosion-Proof Ex d I Mb Certification

Certified as Group I Category M2 equipment for underground mining environments with high risks of methane and flammable coal dust explosion.

Continuous Submerged Operation (IP68)

The electric motor is mounted directly above the pump and cooled by surrounding pumped liquid, rated IP68 for complete submersion.

Direct-Drive Closed Impeller Assembly

The closed impeller is mounted directly onto the motor shaft and protected on the inlet side by a suction cover with a precision brass insert.

Double Mechanical Seal Reliability

Equipped with a dual mechanical seal arrangement that prevents media ingress and preserves internal motor integrity even in slurry-laden liquids.

Ground Continuity & Thermal Safety

Integrated bimetallic thermal limiters guard against overheating while an onboard diode unit provides real-time ground continuity monitoring.

Material Versions

P-BA Material Executions

P-BA pumps are made in two material versions: basic and salt-resistant.

Basic Version

Designed for general mine water dewatering, excavation drainage, and contaminated water containing mechanical suspended solids under standard chemical conditions.

Salt-Resistant Version

Engineered with specialized metallurgy and enhanced corrosion-resistant components to handle aggressive saline mine waters, brine solutions, and chemically active underground effluents.
