  • Spares: 7034-B pistons, valves, seals

Reciprocating Vacuum Pumps V13–V26

Single- and two-stage double-acting gate valve vacuum pumps feature water-cooled cylinders. Series V13–V26 serve distillation, filtration, and drying at 200–4,000 m³/h down to < 1.07 mbar. Spares include crossheads, slide valves, valve plates, rod packings, and oil pumps.

  • Single-stage V25–V13: < 13.3 mbar ultimate vacuum
  • Two-stage V26, V20, V16: < 1.07 mbar vacuum
  • Capacity 200 to 4,000 m³/h, E-Exe option
  • Spares: slide valves, rod packings, rods

Reciprocating Duplex Steam Pumps

Horizontal duplex steam pumps 2 PDH 150/120-Z serve boiler feed, marine transfer, and petrochemical plants. Their direct-acting drive runs on live steam up to 16 bar or compressed air without electric motors. Service spares cover piston assemblies, rods, valves, and seal kits.

  • Model 2 PDH 150/120-Z: 25 m³/h delivery
  • Discharge pressure 20 bar, steam 16 bar
  • Stroke 150 mm, pistons 120/180 mm, 393 kg
  • Operates on live steam or compressed air

Rotary-Kiln & Mill Gear Drive Units

Custom gear drive units Vakoma 4640V, 317V-4N, 1606V, and 2535V-4 meet DIN 3990 with KA 2.0 and ratings up to 1,600 kW. They replace legacy DD4640, DD3170, ZM1600, and D3500 drives on rotary kilns and mills. Engineering, adapter frames, and overhauls run jointly with GearTec AG.

  • Replacements for DD4640, DD3170, DD3200, DD2400
  • Replacements for ZM1600, ZM2000, D3500, A2800
  • DIN 3990 factor KA 2.0, bearings > 100,000 h
  • Adapter frames matching existing foundations

Turbo Gear Drives & Legacy GDR Spares

This division builds high-speed turbo gear units ETU40 / ETU 40-1 (625 kW, 9,063 / 1,470 rpm) and TGL 21895 epicyclic drives. Replacement parts also support legacy GDR dosing pumps, compressors, and turbo compressors. Service stock covers gear sets, shafts, bearings, and housings.

  • Turbo gear ETU 40-1: 625 kW, ratio 6.147
  • Epicyclic gears TGL 21895, RUAV 56, A40
  • GDR compressors: 1HS, HV1, 2V1, DIKO 4/8
  • Turbo compressors NA, GR, VRZ, VRK, ZTB

Compressor & Vacuum Pump Selection by Process Duty

VAKOMA Industries (VAKOMA) builds air-cooled Vee-type high-pressure units A2 HV1 and A4 HV1 100/140 (up to 160 bar, 50 m³/h) for switchgear and pressure testing, alongside 42/70 series single-stage (10 bar) and two-stage (16 bar) blocks and 60–250 L receiver packages.

Water-cooled double-acting reciprocating vacuum pumps cover capacities from 200 to 4,000 m³/h with ultimate vacuum below 13.3 mbar (single-stage V25–V13) or below 1.07 mbar (two-stage V26, V20, V16), including E-Exe flameproof enclosures.

Drop-In Gear Drive Replacements for Kilns, Mills & Turbomachinery

Executed with GearTec AG, adaptive replacement drives substitute legacy GDW, SKET, Mafa Dessau, and Peniger units without major foundation rework. Designs such as Vakoma 4640V-1/2, 317V-4N, 1606V-1/2, 2535V-4, and ETU 40-1 follow DIN 3990 (KA 2.0) and ground involute gearing.

Upgrading from plain journal bearings to antifriction bearings rated for > 60,000 to > 100,000 h lowers gear weight and simplifies long-term maintenance across cement and mineral-processing plants.

Spare Parts & Legacy G.D.R. Machinery Support

Spare parts schedules cover VAKOMA vacuum pumps (crossheads, slide valves, valve plates, rod packings, oil pumps), A4 HV1 and 42/70 compressors, 2 PDH steam pumps, and legacy G.D.R. compressors, dosing pumps, turbo compressors (NA, GR, VRZ, VRK), and gearboxes.

Matching replacement parts or adaptive gear drives requires the unit type designation, serial number, motor rating, input/output speeds, transmission ratio, and mounting dimensions from the nameplate or drawing.
