Daikin hydraulic pump model codes: how to order the right replacement
Here’s a mistake that costs real money. A buyer sends “Daikin pump, 23 cc” to three suppliers, gets three quotes, and orders the cheapest. The pump arrives with the wrong control type and the wrong port layout. The model code on the nameplate would have prevented all of it. This guide shows how to read a Daikin hydraulic pump code and order the right match. Advance Hydraulic Works imports and trades hydraulic pumps from Delhi NCR, and a clean model code is the first thing we ask for.
What is a Daikin hydraulic pump?
Daikin makes several hydraulic pump families. The two most common in Indian workshops are variable displacement piston pumps (the V series) and vane pumps. A distributor describes the V series as variable displacement piston pumps from 8 to 70 cc per revolution, with low noise and high efficiency.
The vane range works differently. A listing for one model describes a single-stage vane pump with low noise, small pulsation and a pressure-balanced structure.
Reading a Daikin piston pump code
A Daikin piston pump code packs a lot into a few characters. Take real examples from public listings: V8A1RX-20, listed with pressure compensator control, clockwise rotation, side port and 8 cm³ per revolution. Another is J-V23A4RX-30, listed as a pressure compensator pump with side port and 23 cm³ per revolution.
From these you can see a pattern. The number after “V” tracks displacement, so V8 is 8 cc and V23 is 23 cc. The “R” appears in listings that mention clockwise rotation. The letters and numbers after that point to control type, ports and design details.Don’t deal with that as a full decoder, due to the fact the exact that means of every individual belongs in Daikin’s catalogue. Use the code to slender matters down, then affirm in opposition to the catalogue or along with your supplier.
Be careful with codes that look similar. One listing shows J-V38A3RX-95S1X31 at 37.7 cm³ per revolution with anti-rust paint, so a V38 isn’t literally 38 cc. Small differences like that are exactly why you copy the whole code.
Reading a Daikin vane pump code
Vane pump codes comply with a extraordinary sample, together with DVSB-3V-20 and DVSB-6V-20. The characters suggest some thing exceptional from the piston codes, so in no way practice piston logic to a vane pump. Confirm the entire code together with your provider and the catalogue
The method: code, specs, fit
This is how we’d handle any Daikin hydraulic pump enquiry at Advance Hydraulic Works.
Code. Copy the full model code exactly as printed, including every suffix.
Specs. Add working pressure, motor rpm and the machine type.
Fit. Compare shaft, flange, ports and rotation against the machine.
A worked example
Take a pump coded V38, listed at about 37.7 cc per revolution, on a 1,450 rpm motor. Flow is 37.7 × 1,450 = 54,665 cc a minute, about 54.7 litres per minute. At 140 bar, hydraulic power is roughly 140 × 54.7 ÷ 600, about 12.8 kW. So the motor must be rated well above that. Now suppose someone offers a “similar” 23 cc pump. Flow drops to about 33 litres per minute, and your machine runs about 40% slower. That’s why displacement in the code matters. This is illustrative arithmetic, not a spec sheet, so check against the real model data.
Implementation steps
- Photograph the nameplate in precise light, with the oil wiped off.
- Write down the entire version code, person by way of individual.
- Note working pressure, motor rpm and rotation direction.
- Send the photos and details to Advance Hydraulic Works.
- Ask for the code to be matched, and for availability to be checked.
- When the pump arrives, evaluate its nameplate together with your order, individual via person.
- Check shaft, flange and ports against the antique pump before you in shape it.
- Clean the tank, alternate filters, top the pump and start at low strain.
The usual mistakes are accepting a “close enough” code, wrong rotation and a dry start.
FAQs
How do I read a Daikin hydraulic pump model code?
The number after “V” generally follows displacement, and other characters cover rotation, control and ports. Confirm the exact meaning in Daikin’s catalogue or with your supplier.
What is the distinction among a Daikin piston pump and a Daikin vane pump?
A piston pump fits better stress and variable drift. A vane pump suits constant, medium-strain duty with easy go with the flow. Both are regarded for quiet running.
Can I order a Daikin pump with only the cc size?
No. Displacement alone doesn’t give you control type, rotation or port layout. Send the full code.
Where can I purchase a Daikin hydraulic pump in India?
Look for a dealer who asks for the entire code and your device details earlier than quoting. Advance Hydraulic Works takes enquiries for Daikin pumps and may check availability once you send the model code.
What if my nameplate is lacking?
Photograph the pump from numerous facets, plus the shaft and flange, and describe the system. A supplier can often narrow the options from that.
Your next step
Photograph the nameplate and send the full model code to Advance Hydraulic Works along with your working pressure and machine type. You’ll know exactly what you’re ordering before you pay.
