DIN 24255/6 · ISO 2858 · Back pull-out design · Up to 2500 M³/hr · Up to 180 m head
The BPC Series back pull-out chemical pump from Shubham Industries, Ahmedabad, is a horizontal end-suction centrifugal pump built to DIN 24255/6 and ISO 2858, the global dimensional standard for industrial process and chemical pumps. The back pull-out design allows the complete rotating assembly, including impeller, shaft, mechanical seal, and bearing bracket, to be removed from the rear of the pump without disconnecting suction or delivery pipework. This makes seal and impeller maintenance practical in chemical plant environments where connected pipework cannot be disturbed. The BPC handles clear water, volatile chemicals, acids, alkalis, slurries with solids up to 15 mm, pulp stocks up to 5% consistency, and temperatures up to 200°C with application-specific material selection. Manufactured at Kuha, Ahmedabad, Gujarat; ISO 9001:2015 certified since 1987.

Back Pull-Out Design
A back pull-out pump is a centrifugal pump where the rotating assembly, including impeller, shaft, mechanical seal, and bearing bracket, withdraws axially from the rear of the casing without disturbing suction pipework, delivery pipework, or flanged connections.
DIN 24255/6 and ISO 2858 define the dimensional standard for industrial end-suction centrifugal pumps. This makes the BPC suited for process plants where maintenance access, standard footprints, and pipework stability matter.
In process plants, suction and delivery pipework is fixed into structures and often lagged. The BPC back pull-out design withdraws the rotating assembly from the rear, giving seal and impeller access without moving pipework or disturbing flange alignment.
The BPC is dimensionally compliant with DIN 24255/6 and ISO 2858. This supports like-for-like installation planning and reduces spares complexity where DIN/ISO process pumps are already installed.
A single BPC platform covers water, volatile chemicals, acids, alkalis, corrosive slurries with solids up to 15 mm, pulp stocks up to 5%, and temperatures up to 200°C with application-specific MOC selection.
Configure BPC Series
BPC pump selection is based on duty type, flow, head, liquid temperature, and chemical compatibility. These determine the correct MOC, seal type, delivery bore, drive, and supply arrangement.
For quotation support only. MOC and seal selection require chemical compatibility review by Shubham Industries engineers.
Available Arrangements
BPC pumps can be supplied as bare pump, coupled pump set, stainless construction, fabricated rolled stainless casing, trolley mounted, engine driven, FLP motor arrangement, or custom process assembly where applicable. Final arrangement depends on duty point, motor rating, site layout, MOC, seal, and application conditions.
Rolled stainless steel / fabricated casing BPC for special chemical and process duty where fabricated stainless construction is required.
Regular stainless back pull-out chemical process pump for SS-compatible chemical and industrial process duty.
Standard BPC back pull-out process pump configuration for chemical, water, process, slurry, and industrial transfer duty.
BPC coupled with motor, coupling, and base frame for complete process pump set supply.
Heavy-duty BPC coupled arrangement for higher power process duty and large flow/head requirements.
Mobile arrangement is reviewed where applicable against site layout, duty point, motor rating, and base-frame requirement.
Engine driven arrangement is reviewed where electrical supply or site condition requires non-standard drive selection.
FLP motor arrangement is reviewed where hazardous area classification applies and motor certification details are provided.
Custom coupled assembly with motor, coupling, base frame, and site-specific arrangement is available on request after duty review.
Technical Specifications
The BPC Series handles flows up to 2500 M³/hr and heads up to 180 meters across the full range. Temperature to 200°C, solids to 15 mm, pulp to 5% consistency, and DIN 24255/6 plus ISO 2858 compliance are represented in the standard range.

Applications
The BPC Series is used across chemical plants, process industries, paper and pulp mills, power stations, sugar mills, and municipal installations where a DIN/ISO standard back pull-out pump with application-specific MOC is required.
Transfer of acids, alkalis, dyes, hydrocarbons, and volatile process chemicals. Chemical and petrochemical plant process duty with application-specific MOC based on chemical compatibility.
Pulp stock pumping up to 5% consistency, green liquor, black liquor, heavily contaminated process liquids, raw sewage handling, and chlorinated water circulation.
Corrosive slurries with solid particles up to 15 mm, dyeing and textile slurry circuits, mine drainage with suspended solids, and effluent treatment slurry duty.
Power station service water, cooling water, booster service, fire fighting systems, sprinkler duty, and air conditioning cooling water.
Sugar industry process liquids, food industry liquid transfer, sea water desalination plant feed and transfer, and absorption plant service.
Mine drainage carrying turbid water and suspended solids, construction drainage, oils and brine transfer, and general industrial dirty water handling.
For liquids attacking all metal alloys, specify HPP or FLC after compatibility review. For thermic fluid or hot oil above 200°C, specify TFC. For very large volume above 2500 M³/hr, confirm with engineers because higher capacity is on request. For compact inline installation, specify ILC. Always confirm chemical compatibility and MOC with engineers before ordering.
Selection Guide
The BPC is the correct specification when DIN/ISO interchangeability, back pull-out maintenance access, and wide chemical duty range are required together.

Both BPC and SCC handle chemical and process liquids where stainless construction is compatible. BPC is built to DIN 24255/6 and ISO 2858, offering back pull-out maintenance, slurry and pulp capability, and temperature to 200°C. Choose BPC when DIN/ISO compliance, back pull-out access, or slurry duty is required.
View SCC SeriesChoose by duty
BPC uses application-specific metal construction. HPP uses full polymer wet-end construction with no metal in contact with liquid. Choose HPP when the liquid attacks all metal alloys; choose BPC when a compatible metal MOC can be confirmed.
