NSQ-DHF(T) Horizontal Variable Frequency Drive Pump

Horizontal multistage variable-frequency booster pump NSQ-DHF

NSQ-DHF(T) Horizontal VFD Booster Pump is a variable frequency drive (VFD) booster pump (single pump) by Dooch (South Korea, est. 1996).

Operating range: flow rate up to 29 m³/h, head up to 68 m, motor power 0.37–5.5 (0.5–7.5HP) kW. Each pump is controlled by its own individual VFD (multi-master) to maintain stable discharge pressure according to actual demand, saving energy and alternating operation to extend pump set service life.

Thái Khương Pumps is the authorized distributor in Vietnam (via EPSSO) — technical consultation for model selection based on flow rate/head & quotation: 0941.400.488.

Questions frequently asked

How does the NSQ-DHF(T) handle control and energy savings?
Each pump in the NSQ-DHF(T) set is controlled by its own NSQ-Drive VFD (a "multi-master" setup per Dooch's own literature) rather than a single shared central drive — this keeps discharge pressure stable to actual demand instead of constant on/off cycling, saves energy, and lets the pumps alternate operation to reduce system wear. The setup also lets the system keep running if one pump fails.
What parameters should be used to select the NSQ-DHF(T)?
You need to determine the required flow rate (m³/h) and head (m) at the point of use, the number of pumps in the set, the available power supply (3-phase or single-phase) and grid frequency (50Hz/60Hz). Send your actual operating conditions and a TKT engineer will select the right NSQ-DHF(T) configuration and send a quotation. Contact 0941.400.488.
How does the NSQ-DHF(T) differ from the NSQ-DHM?
The NSQ-DHF(T) uses a multistage horizontal centrifugal pump, reaching a head of up to 68 m at a flow rate of up to 29 m³/h — suited to projects that need to push water higher or farther. The NSQ-DHM uses a singlestage horizontal centrifugal pump, a simpler build, lower head (up to 30 m) at a flow rate of up to 26 m³/h, and a smaller motor power range — suited to smaller-scale boosting with a shorter discharge run, prioritizing a compact setup and lower upfront cost.
What material and standards does the NSQ-DHF(T) meet?
Per Dooch's own literature, the NSQ-DHF(T) pump body is stainless steel. Dooch is a Korean manufacturer since 1996, holding company-level KS Q ISO 9001:2015, CE, WRAS and NEP certifications, and develops its own pump-dedicated VFD (NSQ-Drive) rather than using a generic industrial drive.
What should be considered when installing the NSQ-DHF(T)?
Mount the pump on a flat, solid base; fit shut-off valves on both the suction and discharge sides so maintenance does not require draining the whole system. The NSQ-Drive control cabinet should be placed in a dry, ventilated location, away from direct sunlight and high humidity, to protect the electronic components' service life.
How is the NSQ-DHF(T) maintained periodically?
Periodically inspect the mechanical seal, check valve and suction strainer to prevent clogging; monitor the parameters shown on the NSQ-Drive (pressure, current) per the manufacturer's recommendation. TKT supplies genuine replacement parts when needed.
Where to purchase a genuine NSQ-DHF(T) and get warranty service?
Thai Khuong Pumps is a genuine Dooch distributor in Vietnam (via EPSSO PUMPS — the Dooch brand representative for Vietnam & Southeast Asia). TKT supplies genuine equipment, technical advice, installation, NSQ-Drive cabinet setup, commissioning and manufacturer-policy warranty. Hotline 0941.400.488.
