Model specifications and technical analysis of DENISON T7EDS series vane pumps：
1. Model structure and technical parameters
Typical model example
T7EDS-085-B38-1R03-A1M0：
085-B38: Double pump displacement combination (85 cc/rev + 38 cc/rev).
1R03: Flange installation configuration (special direction), the shaft end is a flat key or a 1:10 taper keyway.
A1M0: NBR seal (resistant to mineral oil-based hydraulic oil).
T7EDS-045-B35-1R00-A1M0：
045-B35: Displacement combination (45 cc/rev + 35 cc/rev).
Core performance parameters
Item value remarks
The maximum working pressure is 300 bar (double pump configuration), the peak pressure of a single pump can reach 320 bar
Speed range 600~2800 rpm industrial standard configuration
Displacement range 5.8~269 cm3/rev covers small flow to large flow requirements
Volumetric efficiency ≥92% (at 1800 rpm), typical mechanical efficiency is 0.94
2. Technical differences and application scenarios
T7EDS series features
High pressure optimization: Designed for high pressure systems, it enhances sealing performance compared to the T7D series (the suffix “S” may represent a special sealing design).
Modular design: supports double or multiple configurations, and adapts to complex hydraulic circuits.
Application area
Industrial equipment: high-pressure hydraulic drives such as presses, bending machines, shearing machines, etc.
Metallurgy and shipbuilding: heavy-duty scenarios such as rolling equipment and deck machinery.
Process steps：
Customer inquiry: Customers will make inquiries before placing an order to understand product details and communication needs.
Quotation: According to customer needs, provide a formal quotation, including the name, model, quantity, delivery time, payment method, etc. of the goods.
Order confirmation: After the customer confirms the quotation, a formal purchase order will be placed.
Confirm the delivery time: communicate the delivery time with the production department, inform the factory of the order details, and arrange the production plan.
Sign an export contract: After the two parties confirm that it is correct, sign an export contract to establish a trade relationship.
Implement the letter of credit (if applicable): If the payment method of the letter of credit is used, the customer needs to be urged to issue the certificate and review the contents of the letter of credit.
Export stocking: According to the requirements of the contract and the letter of credit, arrange production, purchase raw materials and packaging, and prepare the goods.
Chartering and booking: Contact the freight forwarder to make a booking and arrange the transportation of goods.
Export inspection: Apply to the quality inspection department for export commodity inspection and provide relevant documents.
Apply for a write-off slip: apply for a write-off slip from the foreign exchange management department for subsequent foreign exchange write-off.
Export declaration: Declare exports to the customs and provide documents such as power of attorney for customs declaration, customs declaration form for export goods, commercial invoice, packing list, etc.
