TZPM 100–2000, ZPM 250–1700, TZPM HB and ZPM HB: identify valves, seats, diaphragms, seals and reciprocating-drive parts by pump model, flow, pressure and temperature.
Use this guide to identify GEHO piston diaphragm pump spares for drawing-based supply. First confirm the installed pump from its full model, serial number, flow, discharge pressure, temperature and pumped medium. Then confirm manufacturing requirements using the general arrangement, BOM, drawing, valve and cylinder positions, used parts and maintenance records.
TZPM and ZPM model ranges, flow, pressure, power, temperature and assembly weights follow Weir's current product pages. Heat Barrier entries are limited to the design and temperature range confirmed by the manufacturer.
| Model / series | Design | Published flow | Published pressure / power | Temperature / assembly weight |
|---|---|---|---|---|
| TZPM 100–2000 | Triplex, single-acting, crankshaft-driven | 10–1,500 m³/h | 1,500–30,000 kPa; 100–4,000 kW | −40–+120°C; assembly approximately 5–240 t |
| ZPM 250–1700 | Duplex, double-acting, crankshaft-driven | 10–800 m³/h | 1,500–30,000 kPa; 10–2,500 kW | −40–+120°C; assembly approximately 3–120 t |
| TZPM HB | Triplex, single-acting, Heat Barrier | Project-specific | High-temperature, high-pressure process pumping | Typical hot-slurry range: 150–250°C |
| ZPM HB | Duplex, double-acting, Heat Barrier | Project-specific | High-temperature, high-pressure process pumping | Typical hot-slurry range: 150–250°C |
The manufacturer identifies check valves as the principal wear parts in direct contact with slurry. Diaphragms, seals and cylinder liners require separate assessment according to their isolation, pressure-retaining and maintenance functions; they should not all be treated as ordinary pump liners.
Suction & Discharge Non-return Valves
Check valves are the main wear components in direct contact with abrasive slurry. Confirm the pump model, valve position, flow direction, body connections, internal valve design, pressure and medium.
Send valve details →Valve Seat, Guide & Spring
Valve-seat sealing faces withstand particle erosion and repeated impact; guides and springs control opening and closing. Confirm the suction or discharge side, installation direction, mating dimensions and complete valve assembly.
Send valve-seat details →
Preformed Diaphragm
The diaphragm separates abrasive slurry from the piston, cylinder liner and hydraulic side. When ordering, confirm the pump model, diaphragm chamber, profile, clamping interface, stroke, medium, temperature and replacement history.
View the component guide →Diaphragm Housing, Cover & Clamp Seal
The housing and cover retain pressure and secure the diaphragm edge. Confirm the pump model, cylinder position, flanges, bolt holes, seal grooves, wetted-side material and pressure rating.
Send housing and cover details →
Piston Seal & Cylinder Liner
Isolated from slurry by the diaphragm, piston seals and cylinder liners operate in hydraulic fluid. Confirm the bore, stroke, seal section, grooves, liner dimensions, surface condition and hydraulic fluid.

Heat Barrier Separator & Cooling Section
These components apply only to TZPM HB or ZPM HB high-temperature service. The separator, cooling section and diaphragm section work together to limit heat transfer to moving parts. Do not assume this arrangement applies to standard T/ZPM pumps.
Send Heat Barrier component details →Drive components and auxiliary systems are assessed separately. Check crankshafts, connecting rods, pistons, bearings, gearboxes, pulsation dampeners and controls against the full pump model and installed interfaces.
Piston, Piston Rod & Crosshead
These parts transmit the crank mechanism's reciprocating motion to the hydraulic side. Confirm the pump model, cylinder position, stroke, rod diameter, connecting threads, crosshead sliding surfaces and assembly datums.
View the component guide →Crankshaft, Connecting Rod & Bearing Shell
The crank mechanism operates continuously under high reciprocating loads. Confirm the full model, cylinder position, crank throw, drive side, journal dimensions, balance requirements and lubrication passages.
View the component guide →Main & Roller Bearings
These bearings support the crankshaft and reciprocating mechanism. Supply the full bearing designation, internal clearance, cage, pairing arrangement, locating or floating position and lubrication requirements.
View the component guide →
Gearbox, Coupling & Drive Interface
The crankshaft is generally driven by a motor and gearbox with variable-frequency control. Confirm power, speed, gear ratio, shaft extension, rotation direction, coupling, base and guard interfaces.
View the component guide →Pulsation Dampener & Nitrogen Control Parts
Nitrogen-precharged dampeners smooth pipeline pressure as operating conditions change. Confirm volume, design pressure, precharge pressure, bladder or diaphragm, valves, flanges and instrument connections.
Lubrication, Diaphragm Control & Instrumentation
Auxiliary systems maintain bearing lubrication and diaphragm position and monitor operation. Check pumps, valves, filters, sensors, pressure gauges, piping and electrical interfaces against the control-system version.
Send auxiliary-system details →No. Provide the full numeric model, serial number, cylinder position, suction or discharge valve position, pressure, temperature, medium, drawing, used-part dimensions and maintenance records. Project configurations can differ within the same series.
No. The manufacturer explains that the diaphragm isolates slurry from moving parts. Check valves in direct contact with slurry are the main wear parts. Assess diaphragms, seals, cylinder liners, pistons and drive parts separately by function and failure mode.
Part numbers are published only when supported by traceable manufacturer catalogues, drawings, BOMs or installation records. Send the nameplate, full pump model, drawing, valve position, and used-part photographs and dimensions for checking.
Provide the full model, serial number, cylinder position, suction or discharge valve position, flow, pressure, temperature, medium, drawings or samples, and used-part photographs and dimensions. These support identification, material assessment, manufacturing coordination, quality control and finished-part delivery.
