Engineering heritage and positive displacement mechanics of BSM gear pumps

Industrial positive displacement rotary gear pumps by BSM Pump Corporation are engineered for uninterrupted circulation of lubricating oils and hydraulic fluids throughout manufacturing plants.

Unlike conventional centrifugal units, positive displacement gear pumps deliver uniform fluid volume under high discharge pressure irrespective of liquid viscosity fluctuations.

Tracing its engineering lineage back to 1883 within Brown and Sharpe, the manufacturer produces optimized gear meshing designs that minimize vibration and ensure long gear tooth wear endurance.

Factory assembly incorporates strict mechanical verification of gear center distances, radial tip clearances and precision sleeve bearing alignment across every production unit.

Heavy duty and 500 series assemblies for elevated fluid viscosity

For demanding conditions across rolling mills, energy generation plants and heavy machinery gearboxes, BSM builds Heavy Duty and 500 series pump assemblies.

These units are rated for discharge pressures up to two thousand psi and reliably circulate viscous lubricants with ratings reaching one million SSU.

The incorporation of herringbone gear tooth geometry cancels internal axial thrust on drive shaft bearings and reduces hydraulic noise under high rotational speeds.

Rigid heavy-wall housings produced from high-tensile iron and alloy steel deliver superior structural stiffness during cyclic hydraulic pressure spikes in industrial plant piping systems.

Automatic reversing vane pumps engineered for bi-directional machine spindles

A standout technological feature of the BSM portfolio is the automatic reversing vane series including Models 50 and 100 developed for machinery with bi-directional drive shafts.

When a machine tool spindle or lead screw reverses rotation direction, the internal eccentric mechanism inside the pump automatically shifts fluid port orientation.

This mechanical action ensures continuous unidirectional oil discharge toward critical friction bearings without requiring external solenoid directional valves.

Compact physical dimensions and standardized flange mountings allow direct mounting onto lathe headstocks and machine tool transmission gearboxes.

Corrosion resistant metallurgy in grade 316 stainless steel and bronze

In chemical, pharmaceutical and marine environments, industrial operators rely on BSM rotary gear pumps manufactured from grade 316 stainless steel and phosphor bronze.

These corrosion-resistant metallurgical alloys prevent chemical degradation when handling salt solutions, organic acids, fats and aggressive industrial compounds. Precision machining of internal gear teeth prevents localized pitting and hydraulic cavitation wear within internal flow chambers.

Drive shafts are fitted with mechanical face seals featuring silicon carbide rings and Viton elastomers, securing absolute fluid containment during hazardous chemical transfer.

Centrifugal coolant pump assemblies for reliable machine tool fluid delivery

To ensure continuous heat removal from machining zones across milling, grinding and turning centers, BSM offers centrifugal coolant pumps including Centrifugal series and Models 11, 12, 13.

The semi-submersible architecture with rigid vertical column pipes allows fluid elements to sit inside coolant tanks while shielding the electric motor from liquid immersion.

Open and semi-enclosed impeller profiles easily tolerate fine metal shavings and abrasive grinding particulate without loss of delivery head or volume. The equipment delivers uniform coolant stream velocity, preventing thermal damage to expensive precision tooling.

Routine maintenance protocols, precision gear sets and replacement seals

To maintain factory volumetric efficiency across plant pump installations, BSM supplies engineered overhaul packages and replacement components.

Offerings include matched gear pairs in spur, helical and herringbone tooth styles, ground drive shafts, precision sleeve bushings and shaft seal assemblies.

Timely replacement of mechanical seals and sleeve bearings based on operating hour intervals prevents internal slip and preserves discharge pressure ratings.

Specifying replacement components by equipment serial nameplate markings guarantees perfect alignment with original dimensional tolerances and ensures prolonged service intervals.
