High-Pressure Diaphragm Hydrogen Compressors: A 32 MPa Unit to Sweden, and an Imported Brand Replaced at an Industrial Gas Plant
Two deliveries in the same quarter — one export at 32 MPa, one substitution at a hydrogen filling project — plus a published ceiling of 320 MPa.
Lead
A GV-100/17-320 diaphragm hydrogen compressor built by 丰电金凯威（苏州）压缩机有限公司 completed delivery and entered service with a customer in Sweden. Design capacity is 100 Nm³/h and discharge pressure is 32 MPa (4,640 psi). (Source: 中国通用机械工业协会 weekly roundup, 6 September 2026.)
The same company reports a GD-500/14-200 diaphragm hydrogen compressor commissioned at a hydrogen filling project, replacing a machine from the imported PPI brand. (Source: 中国通用机械工业协会, 9 August 2026.)
Facts
The export unit. Model GV-100/17-320, 100 Nm³/h design capacity, 32 MPa discharge pressure. The release states the unit meets ATEX, CU-TR and ASME requirements and that it is intended for a step of the European hydrogen chain, without naming the customer or the project. (Source: 中国通用机械工业协会 weekly roundup, 6 September 2026.)
The substitution unit. Model GD-500/14-200, at a hydrogen filling project for an industrial gas customer whose ownership is described in the same item as foreign-invested (外资) and, in a later sentence, as overseas (海外). The source does not resolve the two descriptions, and does not state the flow, suction pressure or discharge pressure of this model. (Source: 中国通用机械工业协会, 9 August 2026.)
Pressure grades the company lists. First domestic 90 MPa and 250 MPa diaphragm hydrogen compressors; a 55 MPa / 2,000 Nm³/h large-flow diaphragm hydrogen compressor released recently; and 90 MPa, 250 MPa and 320 MPa grades stated to have passed product appraisal organised by the China General Machinery Industry Association. (Source: 中国通用机械工业协会, 9 August 2026.)
Why the two machines are the same story. The diaphragm construction used in both units seals the gas from the hydraulic side, with static seals around the head rather than a piston-rod packing, which is the reason this family is specified where the gas is hydrogen. Both items describe the machines as oil-free, with the gas not in contact with lubricant. (Source: 中国通用机械工业协会, 6 September 2026 and 9 August 2026.)

Note on sourcing. These items report company delivery announcements, as published by the industry association. We record only the verifiable layer — what was delivered, to what kind of project, at what pressure. We do not rank suppliers, we do not recommend one, and we do not repeat performance claims from company material.
What the source does not state
Neither item names the customers. Neither gives the gas purity, the suction pressure, the duty cycle or the number of machines at either site. The GD-500/14-200 item does not state the flow or the pressure ratings of that model, and it describes the customer's ownership in two different ways within the same item. No price, order value or delivery date is given for either machine.
